[jira] Commented: (NUTCH-694) Distributed Search Server fails
[ https://issues.apache.org/jira/browse/NUTCH-694?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12674962#action_12674962 ]
Dr. Nadine Hochstotter commented on NUTCH-694:
----------------------------------------------
Hi Sami,
I tried the patch, but it didn't work for me. Probably, because I don't use Nutch in PseudoDistributedMode on a single server?

> I run Nutch on a single server, I have two crawl directories, that's why I use Nutch in distributed search server mode as described in the hadoop manual.
> But since I have a new Trunk Version (04.02.2009) it fails. Local search on one index works fine. But distributed search throws following exception:
> In catalina.out (server)

> We do not run Nutch in PseudoDistributedMode. We only use the distributed search mode. With Nutch-0.9 this was working properly.
