Subject Re: Not information in Job History UI
Date Tue, 04 Mar 2014 00:29:42 GMT
Thanks for that info Jian.

You said, "there are no job logs generated on the server that is running
the job.".  So am I correct in assuming the logs will be in the dir
specified by yarn.nodemanager.log-dirs on the datanodes?

I am quite confused as to where the logs for each specific part of the
ecosystem reside.

If I were to run a job and I wanted to tail the job log as it was running,
where would I find that log?

Thanks for your help.
