12.1. Installing GeoMesa Bigtable

12.1.1. Installing the Binary Distribution

GeoMesa Bigtable 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 (2.1.0) from GitHub.

Extract it somewhere convenient:

# download and unpackage the most recent distribution:
$ wget "https://github.com/locationtech/geomesa/releases/download/geomesa_2.11-$VERSION/geomesa-bigtable_2.11-$VERSION-bin.tar.gz"
$ tar xvf geomesa-bigtable_2.11-$VERSION-bin.tar.gz
$ cd geomesa-bigtable_2.11-$VERSION
$ ls
bin  conf  dist  docs  examples  lib  LICENSE.txt  logs

To run the command-line tools, the configuration file hbase-site.xml must be on the classpath. This can be accomplished by placing the file in the conf folder. For more information, see Connecting to Cloud Bigtable.

12.1.2. Installing GeoMesa Bigtable in GeoServer

Warning

GeoServer 2.13.0 and 2.13.1 are not recommended due to two serious bugs:
  • GeoMesa WPS processes are not triggered correctly, and will run slowly or not at all
  • GeoMesa count optimizations are bypassed, potentially resulting in large duplicate scans for WFS queries

The HBase GeoServer plugin is bundled by default in a GeoMesa binary distribution. To install, extract dist/gs-plugins/target/geomesa-bigtable-gs-plugin_2.11-$VERSION-install.tar.gz into GeoServer’s WEB-INF/lib directory. This distribution does not include HBase or Hadoop JARs - the following JARs should be copied into GeoServer’s WEB-INF/lib directory. For convenience, the script bin/install-hadoop-hbase.sh will download them from Maven Central.

  • hbase-annotations-1.3.1.jar
  • hbase-client-1.3.1.jar
  • hbase-common-1.3.1.jar
  • hbase-hadoop2-compat-1.3.1.jar
  • hbase-hadoop-compat-1.3.1.jar
  • hbase-prefix-tree-1.3.1.jar
  • hbase-procedure-1.3.1.jar
  • hbase-protocol-1.3.1.jar
  • hbase-server-1.3.1.jar
  • commons-configuration-1.6.jar
  • hadoop-annotations-2.5.2.jar
  • hadoop-auth-2.5.2.jar
  • hadoop-client-2.5.2.jar
  • hadoop-common-2.5.2.jar
  • hadoop-hdfs-2.5.2.jar

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

The Bigtable data store requires the configuration file hbase-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). For more information, see Connecting to Cloud Bigtable.

Restart GeoServer after the JARs are installed.

12.1.2.1. Jackson Version

Warning

Some GeoMesa functions (in particular Arrow conversion) requires jackson-core-2.6.x. Some versions of GeoServer ship with an older version, jackson-core-2.5.0.jar. After installing the GeoMesa GeoServer plugin, be sure to delete the older JAR from GeoServer’s WEB-INF/lib folder.
