[jira] [Created] (SPARK-18957) when WAL time out, loss data

xy7 created SPARK-18957:
---------------------------

             Summary: when WAL time out, loss data
                 Key: SPARK-18957
                 URL: https://issues.apache.org/jira/browse/SPARK-18957
             Project: Spark
          Issue Type: Bug
          Components: Block Manager
    Affects Versions: 1.6.2
         Environment: hadoop2.7.1 spark1.6.2
            Reporter: xy7
            Priority: Critical
             Fix For: 1.6.2


When sparkStreaming's blockManager writeAheadLog timeout, it cause keepPushBlocks to be stoped, with this warn log
"WARN scheduler.ReceiverTracker: Error reported by receiver for stream 0: Error in block pushing thread - java.util.concurrent.TimeoutException: Futures timed out after [30 seconds]".
But the receiver continued to get data from MQ, so the data lost. In sparkUI, we would found all the batchs turned to 0 events.
