Review request for Sqoop.

Bugs: SQOOP-3178

Repository: sqoop-trunk


New feature for sqoop-1: Sqoop Incremental Merge for Parquet File Format


  src/java/org/apache/sqoop/mapreduce/MergeGenericRecordExportMapper.java PRE-CREATION 
  src/java/org/apache/sqoop/mapreduce/MergeJob.java 4e2a916 
  src/java/org/apache/sqoop/mapreduce/MergeParquetMapper.java PRE-CREATION 
  src/java/org/apache/sqoop/mapreduce/MergeParquetReducer.java PRE-CREATION 
  src/java/org/apache/sqoop/tool/ImportTool.java c79e044 

Diff: https://reviews.apache.org/r/59346/diff/1/

Testing (updated)


Currently, sqoop-1 only supports merging of two parquet file 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
