[HIVE-14418] Hive config validation prevents unsetting the settings

• Type: Bug
• Status: Closed
• Priority: Major
• Resolution: Fixed
• Fix Version/s: 2.1.1, 2.2.0
• Labels: TODOC2.1.1

Release Note

"-d" option has been added to Hive CLI "reset" command, allowing one to reset specific settings to built-in defaults, overriding any session-specific values, as well as configuration files in use. E.g. "reset -d hive.compute.splits.in.am hive.smbjoin.cache.rows".

Description

hive> set hive.tez.task.scale.memory.reserve.fraction.max=;
Query returned non-zero code: 1, cause: 'SET hive.tez.task.scale.memory.reserve.fraction.max=' FAILED because hive.tez.task.scale.memory.reserve.fraction.max expects FLOAT type value.
hive> set hive.tez.task.scale.memory.reserve.fraction.max=null;
Query returned non-zero code: 1, cause: 'SET hive.tez.task.scale.memory.reserve.fraction.max=null' FAILED because hive.tez.task.scale.memory.reserve.fraction.max expects FLOAT type value.

unset also doesn't work.
