Ted Yu updated HBASE-15073:
---------------------------
Fix Version/s: (was: 1.3.0)
(was: 1.2.0)
(was: 2.0.0)
Release Note: (was: The NORMALIZATION_ENABLED_KEY attribute for table
has been renamed NORMALIZATION_MODE whose value represents the types of action
allowed for normalization.
To enable normalization for the table, you can specify 'M' for merging, 'S' for
splitting or "MS" for splitting / merging.
Leave empty to disable normalization.)
> Finer grained control over normalization actions for RegionNormalizer

> 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 ("N" for disabled, "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) of actions
