            Reporter: Tathagata Das
            Assignee: Tathagata Das
            Priority: Critical


As part of the initiative of preventing data loss on streaming driver failure, this sub-task implements a BlockRDD that is backed by HDFS. This BlockRDD can either read data from the Spark's BlockManager, or read the data from file-segments in HDFS.
