    Description

      Support for variable substitution was added in HIVE-1096. However, variable substitution was implemented by reusing the HiveConf namespace, so there is no separation between Hive configuration properties and Hive variables.

      This ticket encompasses the following enhancements:

      • Create a separate namespace for managing Hive variables.
      • Add support for setting variables on the command line via '-hivevar x=y'
      • Add support for setting variables through the CLI via 'set hivevar:x=y'
      • Add support for referencing variables in statements using either '${hivevar:var_name}' or '${var_name}'
      • Provide a means for differentiating between hiveconf, hivevar, system, and environment properties in the output of 'set -v'
