[jira] [Created] (SPARK-3495) Block replication fails continuously when the replication target node is dead

Tathagata Das created SPARK-3495:
------------------------------------

             Summary: Block replication fails continuously when the replication target node is dead
                 Key: SPARK-3495
                 URL: https://issues.apache.org/jira/browse/SPARK-3495
             Project: Spark
          Issue Type: Bug
          Components: Block Manager, Spark Core, Streaming
    Affects Versions: 1.0.2, 1.1.0
            Reporter: Tathagata Das
            Assignee: Tathagata Das
            Priority: Critical


If a block manager (say, A) wants to replicate a block and the node chosen for replication (say, B) is dead, then the attempt to send the block to B fails. However, this continues to fail indefinitely. Even if the driver learns about the demise of the B, A continues to try replicating to B and failing miserably. 

The reason behind this bug is that A initially fetches a list of peers from the driver (when B was active), but never updates it after B is dead. This affects Spark Streaming as its receiver uses block replication.
