7.1. Installing GeoMesa Accumulo

7.1.1. Installing from the Binary Distribution

GeoMesa Accumulo artifacts are available for download or can be built from source. The easiest way to get started is to download the most recent binary version ($VERSION = 1.3.2) and untar it somewhere convenient. For example, to download and prepare the geomesa-accumulo binary:

# download and unpackage the most recent distribution
$ wget http://repo.locationtech.org/content/repositories/geomesa-releases/org/locationtech/geomesa/geomesa-accumulo-dist_2.11/$VERSION/geomesa-accumulo-dist_2.11-$VERSION-bin.tar.gz
$ tar xvf geomesa-accumulo-dist_2.11-$VERSION-bin.tar.gz
$ cd geomesa-accumulo-dist_2.11-$VERSION
$ ls
bin/  conf/  dist/  docs/  examples/  lib/  LICENSE.txt  logs/

7.1.2. Building from Source

GeoMesa Accumulo may also be built from source. For more information refer to Building from Source in the developer manual, or to the README.md file in the the source distribution. The remainder of the instructions in this chapter assume the use of the binary GeoMesa Accumulo distribution. If you have built from source, the distribution is created in the target directory of geomesa-accumulo/geomesa-accumulo-dist.

More information about developing with GeoMesa may be found in the Developer Manual.

7.1.3. Installing the Accumulo Distributed Runtime Library

The geomesa-accumulo-dist_2.11-$VERSION/dist/accumulo/ directory contains the distributed runtime JARs that contains server-side code for Accumulo that must be made available on each of the Accumulo tablet servers in the cluster. These JARs contain GeoMesa code and the Accumulo iterators required for querying GeoMesa data.


GeoMesa requires commons-vfs2.jar 2.1 or later. This JAR ships with Accumulo 1.7.2+, but for older installations the JAR needs to be updated in $ACCUMULO_HOME/lib on all Accumulo servers.


There are two runtime JARs available, with and without raster support. Only one is needed and including both will cause classpath issues.

The version of the distributed runtime JAR must match the version of the GeoMesa data store client JAR (usually installed in GeoServer; see below). If not, queries might not work correctly or at all. Manual Install

The desired runtime JAR should be copied into the $ACCUMULO_HOME/lib/ext folder on each tablet server.

# something like this for each tablet server
$ scp dist/accumulo/geomesa-accumulo-distributed-runtime_2.11-$VERSION.jar \
# or for raster support
$ scp dist/accumulo/geomesa-accumulo-distributed-runtime-raster_2.11-$VERSION.jar \


You do not need the JAR on the Accumulo master server, and including it there may cause classpath issues later. Namespace Install

Copying the runtime JAR to each tablet server as above will work, but in Accumulo 1.6+, we can leverage namespaces to isolate the GeoMesa classpath from the rest of Accumulo.

To install the distributed runtime JAR, use the setup-namespace.sh script in the geomesa-accumulo-dist_2.11-$VERSION/bin directory.

$ ./setup-namespace.sh -u myUser -n myNamespace

The command line arguments the script accepts are:

  • -u <Accumulo username>
  • -n <Accumulo namespace>
  • -p <Accumulo password>
  • -t <Use a cached Kerberos TGT>
  • -g <Path of GeoMesa distributed runtime JAR> (optional, will default to the distribution folder and without raster support)
  • -h <HDFS URI e.g. hdfs://localhost:54310> (optional, will attempt to determine if not supplied)

Since accumulo shell does not directly support Kerberos keytabs, if using Kerberos (-t) then a cached Kerberos ticket-granting-ticket (TGT) should be obtained using the kinit command.

If -t is specified, -p must not be specified. If both -p and -t are omitted, the user is prompted for a password.

Alternatively you can manually install the distributed runtime JAR with these commands:

$ accumulo shell -u root
> createnamespace myNamespace
> grant NameSpace.CREATE_TABLE -ns myNamespace -u myUser
> config -s general.vfs.context.classpath.myNamespace=hdfs://NAME_NODE_FDQN:54310/accumulo/classpath/myNamespace/[^.].*.jar
> config -ns myNamespace -s table.classpath.context=myNamespace

Then copy the distributed runtime JAR into HDFS under the path you specified. The path above is just an example; you can included nested folders with project names, version numbers, and other information in order to have different versions of GeoMesa on the same Accumulo instance. You should remove any GeoMesa JARs under $ACCUMULO_HOME/lib/ext to prevent any classpath conflicts.


When connecting to a data store using Accumulo namespaces, you must prefix the tableName parameter with the namespace. For example, refer to the my_catalog table as myNamespace.my_catalog.

7.1.4. Setting up the Accumulo Command Line Tools


To use the Accumulo data store with the command line tools, you need to install the distributed runtime first. See Installing the Accumulo Distributed Runtime Library.

GeoMesa comes with a set of command line tools for managing Accumulo features located in geomesa-accumulo_2.11-$VERSION/bin/ of the binary distribution.


You can configure environment variables and classpath settings in geomesa-accumulo_2.11-$VERSION/bin/geomesa-env.sh.

In the geomesa-accumulo_2.11-$VERSION directory, run bin/geomesa configure to set up the tools.

### in geomesa-accumulo_2.11-$VERSION/:
$ bin/geomesa configure
Warning: GEOMESA_ACCUMULO_HOME is not set, using /path/to/geomesa-accumulo_2.11-$VERSION
Using GEOMESA_ACCUMULO_HOME as set: /path/to/geomesa-accumulo_2.11-$VERSION
Is this intentional? Y\n y
Warning: GEOMESA_LIB already set, probably by a prior configuration.
Current value is /path/to/geomesa-accumulo_2.11-$VERSION/lib.

Is this intentional? Y\n y

To persist the configuration please update your bashrc file to include:
export GEOMESA_ACCUMULO_HOME=/path/to/geomesa-accumulo_2.11-$VERSION

Update and re-source your ~/.bashrc file to include the $GEOMESA_ACCUMULO_HOME and $PATH updates.


Please note that the $GEOMESA_ACCUMULO_HOME variable points to the location of the geomesa-accumulo_2.11-$VERSION directory, not the main geomesa binary distribution directory.


geomesa will read the $ACCUMULO_HOME and $HADOOP_HOME environment variables to load the appropriate JAR files for Hadoop, Accumulo, Zookeeper, and Thrift. If possible, we recommend installing the tools on the Accumulo master server, as you may also need various configuration files from Hadoop/Accumulo in order to run certain commands.

GeoMesa provides the ability to provide additional jars on the classpath using the environmental variable $GEOMESA_EXTRA_CLASSPATHS. GeoMesa will prepend the contents of this environmental variable to the computed classpath giving it highest precedence in the classpath. Users can provide directories of jar files or individual files using a colon (:) as a delimiter. These entries will also be added the the mapreduce libjars variable. Use the geomesa classpath command to print the final classpath that will be used when executing geomesa commands.

If you are running the tools on a system without Accumulo installed and configured, the install-hadoop-accumulo.sh script in the bin directory may be used to download the needed Hadoop/Accumulo JARs into the lib directory. You should edit this script to match the versions used by your installation.


See Logging Configuration for information about configuring the SLF4J implementation.

Due to licensing restrictions, dependencies for shape file support and raster ingest must be separately installed. Do this with the following commands:

$ bin/install-jai.sh
$ bin/install-jline.sh

Test the command that invokes the GeoMesa Tools:

$ geomesa
Using GEOMESA_ACCUMULO_HOME = /path/to/geomesa-accumulo-dist_2.11-$VERSION
Usage: geomesa [command] [command options]

For more details, see Command Line Tools.

7.1.5. Installing GeoMesa Accumulo in GeoServer


The GeoMesa Accumulo GeoServer plugin requires the use of GeoServer 2.9.1 and GeoTools 15.1.

As described in section GeoMesa and GeoServer, GeoMesa implements a GeoTools-compatible data store. This makes it possible to use GeoMesa Accumulo as a data store in GeoServer. GeoServer’s web site includes installation instructions for GeoServer.

After GeoServer is running, you will also need to install the WPS plugin to your GeoServer instance. The GeoServer WPS Plugin must match the version of GeoServer instance. The GeoServer website includes instructions for downloading and installing the WPS plugin.


If using Tomcat as a web server, it will most likely be necessary to pass some custom options:

export CATALINA_OPTS="-Xmx8g -XX:MaxPermSize=512M -Duser.timezone=UTC \
-server -Djava.awt.headless=true"

The value of -Xmx should be as large as your system will permit; this is especially important for the Kafka plugin. You should also consider passing -DGEOWEBCACHE_CACHE_DIR=/tmp/$USER-gwc and -DEPSG-HSQL.directory=/tmp/$USER-hsql as well. Be sure to restart Tomcat for changes to take place.

To install GeoMesa’s Accumulo data store as a GeoServer plugin, we can utilize the script manage-geoserver-plugins.sh in bin directory of the GeoMesa Accumulo or GeoMesa Hadoop distributions. ($VERSION = 1.3.2)


If $GEOSERVER_HOME is set, then the --lib-dir parameter is not needed.

$ bin/manage-geoserver-plugins.sh --lib-dir /path/to/geoserver/WEB-INF/lib/ --install

If you prefer to install the GeoMesa Accumulo GeoServer plugin manually, unpack the contents of the geomesa-accumulo-gs-plugin_2.11-$VERSION-install.tar.gz file in geomesa-accumulo_2.11-$VERSION/dist/geoserver/ in the binary distribution or geomesa-$VERSION/geomesa-accumulo/geomesa-accumulo-gs-plugin/target/ in the source distribution into your GeoServer’s lib directory ($VERSION = 1.3.2):

If you are using Tomcat:

$ tar -xzvf \
  geomesa-accumulo_2.11-$VERSION/dist/geoserver/geomesa-accumulo-gs-plugin_2.11-$VERSION-install.tar.gz \
  -C /path/to/tomcat/webapps/geoserver/WEB-INF/lib/

If you are using GeoServer’s built in Jetty web server:

$ tar -xzvf \
  geomesa-accumulo_2.11-$VERSION/dist/geoserver/geomesa-accumulo-gs-plugin_2.11-$VERSION-install.tar.gz \
  -C /path/to/geoserver/webapps/geoserver/WEB-INF/lib/

There are additional JARs for Accumulo, Zookeeper, Hadoop, and Thrift that will be specific to your installation that you will also need to copy to GeoServer’s WEB-INF/lib directory. For example, GeoMesa only requires Hadoop 2.2 or better, but if you are using Hadoop 2.5.0 you should use the JARs that match the version of Hadoop you are running.

There is a script in the geomesa-accumulo_2.11-$VERSION/bin directory ($GEOMESA_ACCUMULO_HOME/bin/install-hadoop-accumulo.sh) which will install these dependencies to a target directory using wget (requires an internet connection).


You may have to edit the install-hadoop-accumulo.sh script to set the versions of Accumulo, Zookeeper, Hadoop, and Thrift you are running.

$ $GEOMESA_ACCUMULO_HOME/bin/install-hadoop-accumulo.sh /path/to/tomcat/webapps/geoserver/WEB-INF/lib/

Restart GeoServer after the JARs are installed. A note about Accumulo 1.8


GeoMesa supports Accumulo 1.8 when built with the accumulo-1.8 profile. Accumulo 1.8 introduced a dependency on libthrift version 0.9.3 which is not compatible with Accumulo 1.7/libthrift 0.9.1. The default supported version for GeoMesa is Accumulo 1.7.x and the published jars and distribution artifacts reflect this version. To upgrade, build locally using the accumulo-1.8 profile. A note about GeoMesa Process


Some GeoMesa-specific WPS processes such as geomesa:Density, which is used in the generation of heat maps, also require geomesa-process-wps_2.11-$VERSION.jar. This JAR is included in the geomesa-accumulo_2.11-$VERSION/dist/gs-plugins directory of the binary distribution, or is built in the geomesa-process module of the source distribution.

7.1.6. Upgrading

To upgrade between minor releases of GeoMesa, the versions of all GeoMesa components must match. This means that the version of the geomesa-distributed-runtime JAR installed on Accumulo tablet servers must match the version of the geomesa-plugin JARs installed in the WEB-INF/lib directory of GeoServer.

We strive to maintain backwards compatibility for data ingested with older releases of GeoMesa, and in general data ingested with older releases may be read with newer ones (note that the reverse does not apply). For example, data ingested into Accumulo with GeoMesa 1.2.2 may be read with 1.2.3.

It should be noted, however, that data ingested with older GeoMesa versions may not take full advantage of indexing improvements in newer releases. If it is not feasible to reingest old data, see Updating Existing Data to the Latest Index Format for more information on updating its index format.
