Subject [jira] [Commented] (HBASE-4855) SplitLogManager hangs on cluster restart.
Date Thu, 24 Nov 2011 04:51:39 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4855?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13156530#comment-13156530
] 

ramkrishna.s.vasudevan commented on HBASE-4855:
-----------------------------------------------

I got 2 different cases 

Case 1:
batch.installed = 4
batch.done = 2, batch.error =0.

Case 2:
batch.installed = 2
batch.done = 1, batch.error =0.
{code}
while ((batch.done + batch.error) != batch.installed) {
{code}
This condition was always true.  I will dig in more and let you know

> 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().
