> 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.
