Setup

1. Place the plugin shared libraries in the plugin directory.

2. For each worker, edit the config.properties file to set the plugin.dir property to the path of the plugin directory.

   If plugin.dir is not specified, the path to this directory defaults to the plugin directory relative to the directory in which the process is being run.

3. Start or restart the coordinator and workers to pick up any placed libraries.

Note: To avoid issues with ABI compatibility, it is strongly recommended to recompile all shared library plugins during OS and Presto version upgrades.
