stack updated HBASE-14367:
--------------------------
Release Note:
This patch adds shell support for region normalizer (see HBASE-13103).
3 commands have been added to hbase shell 'tools' command group (modeled on how
the balancer works):
- 'normalizer_enabled' checks whether region normalizer is turned on
- 'normalizer_switch' allows user to turn normalizer on and off
- 'normalize' runs region normalizer if it's turned on.
Also 'alter' command has been extended to allow user to enable/disable region
normalization per table (disabled by default). Use it as
alter 'testtable', {NORMALIZATION_MODE => 'true'}
Here is the help for the normalize command:
{code}
hbase(main):008:0> help 'normalize'
Trigger region normalizer for all tables which have NORMALIZATION_MODE flag
set. Returns true
if normalizer ran successfully, false otherwise. Note that this command has no
effect
if region normalizer is disabled (make sure it's turned on using
'normalizer_switch' command).

> https://issues.apache.org/jira/browse/HBASE-13103 adds support for setting a
> normalization flag per {{HTableDescriptor}}, along with the server side chore
> to do the work.
> What is lacking is to easily set this from the shell, right now you need to
> use the Java API to modify the descriptor. This issue is to add the flag as a
> known attribute key and/or other means to toggle this per table.
