[jira] [Created] (HBASE-27399) Add config for setting a max actions per normalizer run

Bryan Beaudreault created HBASE-27399:
-----------------------------------------

             Summary: Add config for setting a max actions per normalizer run
                 Key: HBASE-27399
                 URL: https://issues.apache.org/jira/browse/HBASE-27399
             Project: HBase
          Issue Type: Improvement
            Reporter: Bryan Beaudreault


When you enable the normalizer for the first time on an existing table, the next time it runs it can do a massive amount of merges/splits. This can be painful for callers.

Additionally, if someone were to write a large amount of Puts or Deletes it may cause a merge/split storm as well.

We should add a config which allows operators to limit the amount of actions per run. This way the normalizer can work towards its plan gracefully over the course of a few hours rather than all at once.
