      Description

      The task is to provide the basic capability of writing and reading from HDFS disk during "spilling to disk", as a sub task to fulfill "spilling to S3".

      In theory, after the task is done, by changing the HDFS uri to S3 uri in HDFS connector should provide "spilling to S3" functionality.

      Performance issues are to be considered in later tasks.
