Subject org.mortbay.jetty.EofException
Date Thu, 02 Jan 2014 08:56:07 GMT
Hi all

My hadoop version is 1.1.2

I found the following errors in the logs tasktracker
This seems like https://issues.apache.org/jira/browse/MAPREDUCE-5

But, but I found a little different, as Caused by: java.io.IOException:
Connection reset by peer

Whether it is a network problem caused it?
