--------------------------------------
Summary: [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
Reporter: Andrew Purtell
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
out of many may be the source of the hot spotting load.
