Subject [jira] Commented: (HADOOP-736) Roll back Jetty6.0.1 to Jetty5.1.4
Date Wed, 22 Nov 2006 08:35:03 GMT
    [ http://issues.apache.org/jira/browse/HADOOP-736?page=comments#action_12451873 ] 
Devaraj Das commented on HADOOP-736:

Tried the bugfixed release but sort benchmark fails with it (I ran the benchmark twice and
both the times it failed). A whole lot of reduces fail and finally the job is terminated.
I have not analysed why but I think it is not safe to proceed with this version of Jetty (though
they fixed one major bug yesterday but there might be more lurking around). My recommendation
is to roll back.

> There seems to be a problem with the current version of Jetty (6.0.1) in the case where
we are using it for serving map outputs. It becomes very slow after serving a few outputs
and doesn't recover from that state. Tried with the current release of Jetty - 6.1.0(pre1),
but the problem seems to be there even with that release. So roll back to the previous Jetty
version (5.1.4) seems to be right thing to do for now. This is the URL for the Jira issue
