[jira] [Commented] (HBASE-15564) HashTable job supposedly succeeded but manifest.tmp remain

["Dave Latham (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-15564?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15218956#comment-15218956 ] 

Dave Latham commented on HBASE-15564:
-------------------------------------

It's probably best to start on the mailing list with problems you're having, and if we discover an actual bug or improvement to be done, then make a JIRA.

In this case, if the HashTable MapReduce job completed but the manifest was never renamed from manifest.tmp it seems most likely that the HashTable main tool runner process died, was killed, or lost connection to the cluster and so was unable to perform that rename step.  Be sure to leave it running until after completion.  Since all it does afterward is rename the manifest.tmp file after the job succeeds, you can do that yourself if you like.

> I'm using org.apache.hadoop.hbase.mapreduce.HashTable to create hashes for use in SyncTable.  Occasionally, the job page in jobhistory will say the job succeeded, but in my filesystem, I see "manifest.tmp" instead of the expected "manifest".  According to the code[1], the job must have failed, but I don't see failure anywhere.
