             Summary: make it possible to create recoverable accumulator for 
streaming application
                 Key: SPARK-13374
                 URL: https://issues.apache.org/jira/browse/SPARK-13374
             Project: Spark
          Issue Type: Bug
          Components: Streaming
            Reporter: Mao, Wei


currently the accumulator is not recoverable from checkpoint, So if the 
streaming application is restarted or recovery from broken, the information in 
accumulator will be lost.

I would like to create new accumulator interface in StreamingContext to make it 
possible to create recoverable accumulator for streaming application.
