             Summary: Finer grained control over normalization actions for RegionNormalizer
                 Key: HBASE-15073
                 URL: https://issues.apache.org/jira/browse/HBASE-15073
             Project: HBase
          Issue Type: Task
            Reporter: Ted Yu
            Assignee: Ted Yu


Currently both region split and merge actions are carried out during normalization for underlying table.

However, for certain use case(s), it would be desirable to perform only one type of action.
There is one boolean flag, keyed by NORMALIZATION_ENABLED_KEY, per table that enables normalization.

To provide finer grained control, we have several options:

1. introduce another per table flag to indicate which type(s) of actions are allowed ("S" for split only, "M" for merge only and "MS" for both split and merge)
2. introduce another global flag to indicate which type(s) of actions are allowed
3. modify the meaning of existing flag keyed by NORMALIZATION_ENABLED_KEY so that it indicates type(s) actions
