Lars George commented on HBASE-13103:
-------------------------------------
You may be able to force it like so:
{noformat}
hbase(main):035:0> alter 'normtable', {CONFIGURATION =>
{'NORMALIZATION_ENABLED' => 'true'}}
Updating all regions with the new schema...
1/1 regions updated.
Done.
{noformat}
but that is error-prone as you could easily misspell the arbitrary key string.
I vote for proper shell support.
> [ergonomics] add region size balancing as a feature of master

> Often enough, folks miss-judge split points or otherwise end up with a
> suboptimal number of regions. We should have an automated, reliable way to
> "reshape" or "balance" a table's region boundaries. This would be for tables
> that contain existing data. This might look like:
> {noformat}
> Admin#reshapeTable(TableName, int numSplits);
> {noformat}
> or from the shell:
> {noformat}
> > reshape TABLE, numSplits
> {noformat}
> Better still would be to have a maintenance process, similar to the existing
> Balancer that runs AssignmentManager on an interval, to run the above
> "reshape" operation on an interval. That way, the cluster will automatically
> self-correct toward a desirable state.
