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

             Summary: Add checksum for block in Spark
                 Key: SPARK-18188
                 URL: https://issues.apache.org/jira/browse/SPARK-18188
             Project: Spark
          Issue Type: Improvement
            Reporter: Davies Liu
            Assignee: Davies Liu


There is an understanding issue for a long time: https://issues.apache.org/jira/browse/SPARK-4105, without any checksum for the blocks, it's very hard for us to identify where is the bug came from.

We should have a way the check a block from remote node or disk that is correct or not.
