> Create shell command to identify regions with poor locality

> Key: HBASE-17973
> URL: https://issues.apache.org/jira/browse/HBASE-17973
> Project: HBase
> Issue Type: Improvement
> Components: shell
> Reporter: Josh Elser
> Assignee: Josh Elser
> Fix For: 2.0.0

>
> 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.
