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' -- This message is automatically generated by JIRA.
