Nutch Hadoop 0.20 - AlreadyBeingCreatedException

[Eran Zinman <zz...@gmail.com>]

Hi,

I'm getting Nutch/Hadoop exception: AlreadyBeingCreatedException on some of
Nutch parser reduce tasks.

I know this is a known issue with Nutch (
https://issues.apache.org/jira/browse/NUTCH-692?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12717058#action_12717058
)

And as far as I can see that patch wasn't committed yet because we wanted to
examine it on the new Hadoop 0.20 version. I am using latest Nutch with
Hadoop 0.20 and I can confirm this exception still accrues (rarely - but it
does) - maybe we should commit the change?

Thanks,
Eran

Thanks for reporting this - could you perhaps try to apply that patch 
and see if it helps? I hesitated to commit it because it's really a 
workaround and not a solution ... but if it works for you then it's 
better than nothing.
