      Description

      When RM state store entered an unexpected state, one example is YARN-2340, when an attempt is not in final state but app already completed, RM can never get up unless format RMStateStore.

      I think we should support remove individual application records from RMStateStore to unblock RM admin make choice of either waiting for a fix or format state store.

      In addition, RM should be able to report all fatal errors (which will shutdown RM) when doing app recovery, this can save admin some time to remove apps in bad state.
