> 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 'var 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'
