INLINE COMMENTS
  src/main/resources/hbase-webapps/regionserver/regionserver.jsp:22 I can't spot interval
being referred in the jsp anywhere
  src/main/java/org/apache/hadoop/hbase/metrics/RequestMetrics.java:53 What forces the getRequestPerSecond()
to be periodically called? What if it isn't called for a long time - then the req/sec will
not really be for the last few seconds ...

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