[HBASE-25986] Expose the NORMALIZARION_ENABLED table descriptor through a property in hbase-site

• Type: Improvement
• Status: Resolved
• Priority: Minor
• Resolution: Fixed
• Fix Version/s: 2.5.0, 3.0.0-alpha-2, 2.4.5, 1.7.2
• Component/s: Normalizer
• Hadoop Flags: Reviewed

Release Note

New config: hbase.table.normalization.enabled

Default value: false

Description: This config is used to set default behaviour of normalizer at table level. To override this at table level one can set NORMALIZATION_ENABLED at table descriptor level and that property will be honored. Of course, this property at table level can only work if normalizer is enabled at cluster level using "normalizer_switch true" command.

Description

Today if we want to enable region normalizer on a table we have to add the table descriptor "NORMALIZATION_ENABLED" to the table. If we have a lot of tables and we want normalizer to be enabled by default for each table unless disabled explicitly for a table we can't achieve it

Intention here is to set it using a property in hbase-site
