> [hbtop] Top-N heavy hitter user and client drill downs
> ------------------------------------------------------
>
> Key: HBASE-23065
> URL: https://issues.apache.org/jira/browse/HBASE-23065
> Project: HBase
> Issue Type: Improvement
> Components: hbtop, Operability
> Reporter: Andrew Kyle Purtell
> Assignee: Ankit Singhal
> Priority: Major
> Fix For: 3.0.0, 2.3.0
>
>
> After HBASE-15519, or after an additional change on top of it that provides
> necessary data in ClusterStatus, add drill down top-N views of activity
> aggregated per user or per client IP. Only a relatively small N of the heavy
> hitters need be tracked assuming this will be most useful when one or a
> handful of users or clients is generating problematic load and hbtop is
> invoked to learn their identity.
> This is a critical missing piece. After drilling down to find hot regions or
> tables, sometimes that is not enough, we also need to know which application
> or subset of clients out of many may be the source of the hot spotting load.
