Subject Re: Cannot submit Tez application
Date Sun, 11 May 2014 15:04:17 GMT
@Azury Yu, a question - is the hdfs-site and core-site that is configured on the cluster different
that the one in use on the client? Also, is yarn.application.classpath set up such that the
cluster’s hdfs-site and core-site are not in that class path? 

At the moment, it seems like there is a difference which is getting fixed by having the configs
from the client be pushed to the cluster via local resources.

thanks
— Hitesh
