------------------------------------

             Summary: Block replication can by mistake choose driver BlockManager as a peer
for replication
                 Key: SPARK-3496
                 URL: https://issues.apache.org/jira/browse/SPARK-3496
             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


When selecting peer block managers for replicating a block, the driver block manager can also
get chosen accidentally. This is because BlockManagerMasterActor did not filter out the driver
block manager.
