             Summary: Use java.util.HashMap.remove by mistake in 
BlockManagerMasterActor.removeBlockManager
                 Key: SPARK-1583
                 URL: https://issues.apache.org/jira/browse/SPARK-1583
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
            Reporter: Shixiong Zhu
            Assignee: Shixiong Zhu


The following code in BlockManagerMasterActor.removeBlockManager uses a value 
to remove an entry from java.util.HashMap.

      if (locations.size == 0) {
        blockLocations.remove(locations)
      }

Should change to "blockLocations.remove(blockId)".
