------------------------------------

Liyin has commented on the revision "[jira][HBASE-5407][89-fb] Show the per-region level request/sec
count in the web ui".

  Thanks Prakash's comments.  Answer them inline.

INLINE COMMENTS
  src/main/java/org/apache/hadoop/hbase/metrics/RequestMetrics.java:53 In the run function
of the HRegion server will periodically (hbase.regionserver.msginterval) call createRegionLoad,
which will refresh the request/sec metrics. It follows the same way how other metrics get
updated.

  Also when you refresh the web page, this function will be called as well.
  src/main/resources/hbase-webapps/regionserver/regionserver.jsp:22 sure. I will remove them.

> It would be nice to show the per-region level request/sec count in the web ui, especially
when debugging the hot region problem.
