Subject [jira] [Created] (SPARK-4803) Duplicate RegisterReceiver messages sent from ReceiverSupervisor
Date Tue, 09 Dec 2014 21:15:12 GMT
Ilayaperumal Gopinathan created SPARK-4803:
----------------------------------------------

             Summary: Duplicate RegisterReceiver messages sent from ReceiverSupervisor
                 Key: SPARK-4803
                 URL: https://issues.apache.org/jira/browse/SPARK-4803
             Project: Spark
          Issue Type: Bug
          Components: Streaming
            Reporter: Ilayaperumal Gopinathan
            Priority: Trivial


The ReceiverTracker receivers `RegisterReceiver` messages two times
     1) When the actor at `ReceiverSupervisorImpl`'s preStart is invoked
     2) After the receiver is started at the executor `onReceiverStart()` at `ReceiverSupervisorImpl`

Though the 'RegisterReceiver' message uses the same streamId and the receiverInfo gets updated
every time the message is processed at the `ReceiverTracker`, it makes sense to call register
receiver only after the
receiver is started.

or, am I missing something here?
