Vaibhav Aggarwal commented on HIVE-2020: ---------------------------------------- Requested review: https://reviews.apache.org/r/1204/ > 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' > * 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.
