Ted Yu created AMBARI-13109: ------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
