Subject [jira] [Created] (TEZ-3213) Uncaught exception during vertex recovery leads to invalid state transition loop
Date Wed, 13 Apr 2016 18:00:28 GMT
Jason Lowe created TEZ-3213:
-------------------------------

             Summary: Uncaught exception during vertex recovery leads to invalid state transition
loop
                 Key: TEZ-3213
                 URL: https://issues.apache.org/jira/browse/TEZ-3213
             Project: Apache Tez
          Issue Type: Bug
    Affects Versions: 0.7.0
            Reporter: Jason Lowe


If an uncaught exception occurs during a state transition from the RECOVERING vertex then
V_INTERNAL_ERROR will be delivered to the state machine, but that event is not handled in
the RECOVERING state.  That in turn causes a V_INTERNAL_ERROR event to be delivered to the
state machine, and it loops logging the invalid transitions.
