>                 Key: HBASE-4038
>                 URL: https://issues.apache.org/jira/browse/HBASE-4038
>             Project: HBase
>          Issue Type: Improvement
>          Components: Client, regionserver
>    Affects Versions: 0.92.0
>            Reporter: Nicolas Spiegelberg
>            Priority: Minor
>
> We should provide a basic way for end users to operationally diagnose hot row problems.  Thinking about a 2-phase approach:
> 1. Diagnose hot regions
> 2. Inspect those regions/servers to find the hot rows.
> To diagnose hot regions, we could query the master or regionservers for these regions + sort.  To inspect the regions for hot rows, we could write another script to analyze the HLogs on a server and basically do: sort log|uniq -n|sort -n|top
