BUILD SUCCESSFUL

Your Own Plugin

To create your own plugin, you can follow the patterns from the example plugin. Let's take a closer look at it. First, the build.xml:

<project name="pdktest" default="package">
  <property name="plugin.libname" value="pdk-test-udf"/>
  <property name="plugin.title" value="Hive PDK Test UDF Library"/>
  <property name="plugin.version" value="0.1"/>
  <property name="plugin.vendor" value="Apache Software Foundation"/>
  <property name="function.sql.prefix" value="tp_"/>
  <import file="${hive.install.dir}/scripts/pdk/build-plugin.xml"/>
</project>

All this buildfile does is define some variable settings and then import a build script from the PDK, which does the rest (including defining the package and test targets used for building and testing the plugin). So for your own plugin, change the variable settings accordingly, and set hive.install.dir to the location where you've installed the Hive release.

The imported PDK buildfile assumes a few things about the structure of your plugin source structure:

• your-plugin-root
  • build.xml
  • src: contains Java source files
  • test: contains setup.sql, cleanup.sql, and any datafiles needed by your tests

For the example plugin, a datafile onerow.txt contains a single row of data; setup.sql creates a table named onerow and loads the datafile, whereas cleanup.sql drops the onerow table. The onerow table is convenient for testing UDF's.
