Subject Re: org.apache.tez.dag.api.SessionNotRunning
Date Wed, 18 May 2016 17:33:16 GMT
Hi Guys,

Just a update on this issues. I turned on our debugger when running our
jobs. Was able to nail it down to "Connection refused" error. I am not sure
what has caused this error and how it can be prevent. Looking at the
datanodes when the job was running, I did not notice anything wrong. If
anyone has seen this issue and can shred some light on it, that would be
great. Error logs are given below. Interesting thing is it does not happen
every time. It a sporadic occurrence and if we restart our hive job again,
it goes through without any errors.
