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

             Summary: Add a split policy for busy regions
                 Key: HBASE-15429
                 URL: https://issues.apache.org/jira/browse/HBASE-15429
             Project: HBase

             Fix For: 2.0.0, 1.3.0


Currently, all region split policies are based on size of the region. However, in certain cases, it is a wise choice to make a split decision based on number of requests to the region and split busy regions.

A crude metric is that if a region blocks writes often and throws RegionTooBusyExceoption, it's probably a good idea to split it.
