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

             Summary: Avoid merging regions if tables has not reached the state 
where numbers of regions are not split because of number of regions
                 Key: HBASE-26073
                 URL: https://issues.apache.org/jira/browse/HBASE-26073
             Project: HBase
          Issue Type: Improvement
          Components: Normalizer
    Affects Versions: 2.4.4, 1.7.0
            Reporter: Aman Poonia
            Assignee: Aman Poonia


we have a table on a cluster with 100 regions with default split policy 
(SteppingSplitPolicy). This is a small table and will not get loaded with too 
much data. Now if region size of table is smaller than the normalizer target 
region size than there are chances that normalizer will consider the regions 
for merges. But since the number of regions are small split policy will trigger 
split on next flush. This is a continuous loop and our cluster will be busy in 
these two actions.

We plan to consider number of regions and number of regions in creating plans 
for normalizer.
