Ted Yu updated AMBARI-13066: ---------------------------- Priority: Minor (was: Major) > Turn on fsync on close when HBase is installed > ---------------------------------------------- > > Key: AMBARI-13066 > URL: https://issues.apache.org/jira/browse/AMBARI-13066 > Project: Ambari > Issue Type: Improvement > Reporter: Ted Yu > Priority: Minor > > The following two options should be turned on by default when HBase is > installed: > dfs.datanode.synconclose=true - this is to avoid data loss and guarantee HDFS > correctness. By default, HDFS does not fsync file on close. > dfs.datanode.sync.behind.writes=true - sync partial blocks to disk, always > *must* when sync-on-close is on for performance. > Thanks to [~arpitagarwal] for confirmation -- This message was sent by Atlassian JIRA (v6.3.4#6332)
