Nicolas Spiegelberg updated HBASE-4038:
---------------------------------------
Summary: Hot Region : Write Diagnosis (was: Hot Region Diagnosis)
> Hot Region : Write Diagnosis
> ----------------------------
>
> 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
> Assignee: Riley Patterson
> 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
