Hi,
When I was running a job on hadoop with 75% mappers finished, the
jobtracker hung so that I cannot access
jobtrackerserver:7845/jobtracker.jsp and hadoop job -status hung as
well.
Then I stopped jobtracker and restarted it. However, the jobtracker
cannot be started. I received error message from jobtracker.log.out
saying

I have no idea how to solve this problem. The memory on the jobtracker
server seems ok
total used free shared buffers

Can someone help me on this?
Thanks a lot
