Description

Use the following steps to test.

1. Set up ZK as the RM HA store.
2. Submit a job that refers to lots of distributed cache files with long HDFS path, which will cause the app state size to exceed ZK's max object size limit.
3. RM can't write to ZK and exit with the following exception.

2015-07-10 22:21:13,002 FATAL org.apache.hadoop.yarn.server.resourcemanager.ResourceManager: Received a org.apache.hadoop.yarn.server.resourcemanager.RMFatalEvent of type STATE_STORE_OP_FAILED. Cause:

        at org.apache.hadoop.yarn.server.resourcemanager.recovery.ZKRMStateStore$ZKAction.runWithCheck(ZKRMStateStore.java:1083)

In this case, RM could have rejected the app during submitApplication RPC if the size of ApplicationSubmissionContext is too large.
