Subject [jira] [Commented] (HBASE-4855) SplitLogManager hangs on cluster restart.
Date Wed, 23 Nov 2011 21:58:40 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4855?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13156326#comment-13156326

Ted Yu commented on HBASE-4855:
-------------------------------

@Ramkrishna:
Can you post from the log file the following:
{code}
          status.setStatus("Waiting for distributed tasks to finish. "
              + " scheduled=" + batch.installed
              + " done=" + batch.done
              + " error=" + batch.error);
{code}
It is interesting that neither done nor error counts increased. Or maybe their sum became
greater than batch.installed ?

> Start a master and RS
> RS goes down (kill -9)
> Wait for ServerShutDownHandler to create the splitlog nodes. As no RS is there it cannot
be processed.
> Restart both master and bring up an RS.
> The master hangs in SplitLogManager.waitforTasks().
> I feel that batch.done is not getting incremented properly.  Not yet digged in fully.
> This may be the reason for occasional failure of TestDistributedLogSplitting.testWorkerAbort().
