Create a separate namespace for Hive variables ----------------------------------------------
Key: HIVE-2020 URL: https://issues.apache.org/jira/browse/HIVE-2020 Project: Hive Issue Type: Improvement Components: Query Processor Reporter: Carl Steinbach 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' * Provide a means for differentiating between hiveconf, hivevar, system, and environment properties in the output of 'set -v' -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira
