> 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.
