-------------------------------
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.
