Subject: Re: Failed to package using mvn
Hey Sonali,
You should not have to add yarn.rm.hostname to your configuration. You have
applied the wrong patch. Please apply this patch:
https://issues.apache.org/jira/secure/attachment/12634493/SAMZA-182.1.patch
Do not apply
https://issues.apache.org/jira/secure/attachment/12634200/yarn_remote_rm.pa
tch, which is the one that adds yarn.rm.hostname.
Regarding the failed containers, can you take a look at the NM's logs, and see
what it says there?
Cheers,
Chris
