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?
