Prabhu Joseph updated YARN-10287:
---------------------------------
Description:
Update scheduler-conf corrupts the CS configuration when removing queue which
is referred in queue mapping. The deletion is failed with below error message
but the queue got removed and job submission failed and not removed from the
ZKConfigurationStore. On subsequent modify using scheduler-conf, the queue
appears again from ZKConfigurationStore
