16.2. Installing GeoMesa FileSystem

16.2.1. Installing from the Binary Distribution

GeoMesa FileSystem 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 (2.3.2) from GitHub.

Extract it somewhere convenient:

# download and unpackage the most recent distribution:
$ wget "https://github.com/locationtech/geomesa/releases/download/geomesa_2.11-$VERSION/geomesa-fs_2.11-$VERSION-bin.tar.gz"
$ tar xvf geomesa-fs_2.11-$VERSION-bin.tar.gz
$ cd geomesa-fs_2.11-$VERSION
$ ls
bin/  conf/  dist/  docs/  examples/  lib/  LICENSE.txt  logs/

16.2.2. Building from Source

GeoMesa FileSystem 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 distribution. If you have built from source, the distribution is created in the target directory of geomesa-fs/geomesa-fs-dist.

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

16.2.3. Setting up the FileSystem Command Line Tools

After untaring the distribution, you’ll need to either define the standard Hadoop environment variables or install Hadoop using the bin/install-hadoop.sh script provided in the tarball. Note that you will need the proper Yarn/Hadoop environment configured if you would like to run a distributed ingest job to create files.

If you are using a service such as Amazon Elastic MapReduce (EMR) or have a distribution of Apache Hadoop, Cloudera, or Hortonworks installed you can likely run something like this to configure hadoop for the tools:

# These will be specific to your Hadoop environment
. /etc/hadoop/conf/hadoop-env.sh
. /etc/hadoop/conf/yarn-env.sh
export HADOOP_CONF_DIR=/etc/hadoop/conf

After installing the tarball you should be able to run the geomesa-fs command like this:

$ bin/geomesa-fs

The output should look like this:

INFO  Usage: geomesa-fs [command] [command options]

16.2.4. Installing GeoMesa FileSystem in GeoServer


GeoMesa 2.2.x and 2.3.x require GeoServer 2.14.x. GeoMesa 2.1.x and earlier require GeoServer 2.12.x.

The FileSystem GeoServer plugin is bundled by default in the GeoMesa FS binary distribution. To install, extract $GEOMESA_FS_HOME/dist/gs-plugins/geomesa-fs-gs-plugin_2.11-$VERSION-install.tar.gz into GeoServer’s WEB-INF/lib directory. Note that this plugin contains a shaded JAR with Parquet 1.9.0 bundled. If you require a different version, modify the pom.xml and build the GeoMesa FileSystem geoserver plugin project from scratch with Maven.

This distribution does not include the Hadoop JARs; the following JARs should be copied from the lib directory of your Hadoop installations into GeoServer’s WEB-INF/lib directory:

(Note the versions may vary depending on your installation.)

  • hadoop-annotations-2.7.3.jar
  • hadoop-auth-2.7.3.jar
  • hadoop-common-2.7.3.jar
  • hadoop-mapreduce-client-core-2.7.3.jar
  • hadoop-yarn-api-2.7.3.jar
  • hadoop-yarn-common-2.7.3.jar
  • commons-configuration-1.6.jar

You can use the bundled $GEOMESA_FS_HOME/bin/install-hadoop.sh script to install these JARs.

The FileSystem data store requires the configuration file core-site.xml to be on the classpath. This can be accomplished by placing the file in geoserver/WEB-INF/classes (you should make the directory if it doesn’t exist). Utilizing a symbolic link will be useful here so any changes are reflected in GeoServer.

$ ln -s /path/to/core-site.xml /path/to/geoserver/WEB-INF/classes/core-site.xml

Restart GeoServer after the JARs are installed.
