Josh Elser commented on HBASE-17973:
------------------------------------
bq. The patch is committed already but the JIRA status is shown as unresolved.
What is its current status? I need to put an addendum for HBASE-14925, but when
I try running list_regions command, I get the error as
[~karanmehta93], I guess you missed my earlier comment acknowledging that I
broke it and had put up an addendum? :)

Just need to get a +1 here and I can commit the addendum.

> The data locality of regions often plays a large role in the efficiency of
> HBase. Compactions are also expensive to execute, especially on very large
> tables. The balancer can do a good job trying to maintain locality (when
> tuned properly), but it is not perfect.
> This creates a less-than-desirable situation where it's a costly operation to
> take a cluster with spotty poor locality (e.g. a small percentage of
> regionservers with poor locality).
> We already have this information available via the {{ClusterStatus}} proto.
> We can easily write a shell command that can present regions which are
> lacking a certain percentage of locality.
