             Summary: Verify that max logs parameter wouldn't cause premature 
region flush
                 Key: AMBARI-13109
                 URL: https://issues.apache.org/jira/browse/AMBARI-13109
             Project: Ambari
          Issue Type: Improvement
            Reporter: Ted Yu


For hbase, the following relationship should be maintained:

dfs.blocksize * 0.95 *  hbase.regionserver.maxlogs (default 32) > 
hbase.regionserver.global.memstore.upperLimit * HBASE_HEAPSIZE

The rationale is to avoid premature region flush due to log roll which is 
triggered by insufficiently high max logs.

When user changes the values for max logs, memstore upper limit or max heap 
size, we should verify that the above relationship is satisfied.
