Testing
-------

Hi,

Currently, sqoop-1 only supports merging of two parquet format data sets but it doesn't support
to do incremental merge, so I have written a Sqoop Incremental Merge MR for Parquet File Format
and I have tested with million records of data with N number of iterations. Please review
My patch.

Please let me know if there are any mistakes in My patch


Thanks,

Sandish Kumar HN
