Carl Steinbach updated HIVE-2020:
---------------------------------
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 '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'
