[jira] [Created] (HDFS-3020) Auto-logSync based on edit log buffer size broken

Auto-logSync based on edit log buffer size broken
-------------------------------------------------

                 Key: HDFS-3020
                 URL: https://issues.apache.org/jira/browse/HDFS-3020
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: name-node
    Affects Versions: 0.23.0, 0.22.0
            Reporter: Todd Lipcon
            Priority: Critical


HDFS-1112 added a feature whereby the edit log automatically calls logSync() if the buffered data crosses a threshold. However, the code checks {{bufReady.size()}} rather than {{bufCurrent.size()}} -- which is incorrect since the writes themselves go into {{bufCurrent}}.
