Subject [jira] [Commented] (HBASE-4776) HLog.closed should be checked inside of updateLock
Date Sat, 12 Nov 2011 00:10:51 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4776?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13148877#comment-13148877

Ted Yu commented on HBASE-4776:

The above call is needed because the following is called prior to checking closed flag:
      HLog.Writer nextWriter = this.createWriterInstance(fs, newPath, conf);
This change would activate preLogRoll() and postLogRoll() for listeners. Previously listeners
wouldn't have been notified if closed is true upon entering rollWriter().
