Subject Re: Yarn job runs in Local Mode even though the cluster is running in Distributed Mode
Date Wed, 13 Jun 2012 21:26:18 GMT
Hi Marcus,

Sorry i forgot to mention that Job history server is installed and running
and AFAIK resourcemanager is responsible for running MR jobs. Historyserver
is only used to get info about MR jobs.

Thanks,
Anil
