Client Tools Reference

This chapter describes the client tools provided with this release. They all require certain connection information such as the Greenplum Database master host name, port, database name, and role name. These can be configured using environment variables. See Configuring the Command-Line Tools.

The following tools are provided:

  • gpmapreduce (submits Greenplum MapReduce specifications for execution). The gpmapreduce tool and the associated YAML specification will be removed in the next major release (6.x) of Greenplum Database. It is still included to support existing gpmapreduce YAML files.
  • psql (PostgreSQL interactive terminal)
