Project: Hadoop YARN
Issue Type: Improvement

When we use FileSystemRMStateStore as yarn.resourcemanager.store.class, We saw
the following IOexception cause the RM shutdown.
{code}
FATAL
org.apache.hadoop.yarn.server.resourcemanager.ResourceManager: Received a
org.apache.hadoop.yarn.server.resourcemanager.RMFatalEvent of type
STATE_STORE_OP_FAILED. Cause:

enough number of replicas.

It will be better to Improve FileSystemRMStateStore update failure exception
handling to not shutdown RM. So that a single state write out failure can't
stop all jobs .
