Subject Re: Tez 0.8.3 on EMR hanging with Hive task
Date Wed, 15 Jun 2016 15:03:29 GMT
Hello Joze, 

Would it be possible for you to provide the YARN application logs obtained via “bin/yarn
logs -applicationId <appId>” for both of the cases you have seen? Feel free to file
JIRAs and attach logs to each of them.

Seems some jobs hang on Tez and never return. Those jobs show up in the DAG web-ui, but no
progress is reported on UI nor on Hive logs. Any ideas why this could happen? We detect happens
with certain memory configurations, which if missing, the job dies soon (we guess due to OOM).

TezSession has already shutdown. Application xxxxx failed 2 times due to AM Container". We
are not sure can be related to TEZ-2663, which should be solved since version 0.7.1 onwards.
