Description

If an application submittion failed due to its user configuration (e.g invalid resource request), client will try each SubCluster till an exception is thrown out, which shows no active SubCluster is available. This message will mislead user to believe that something is going wrong on subclusters.

This issue is trying to make exception more understandable by passing RM exception message to router.
