Review request for hive.


Changes
-------

Fixed review comments


Bugs: HIVE-7629
    https://issues.apache.org/jira/browse/HIVE-7629


Repository: hive-git


Description
-------

Map Joins between 2 parquet tables are failing since the Mapper is trying to access the columns
of the first table(bigger table) while trying to load the  second table(smaller map join table).
Fixed this by adding a guard on the column indexes passed by hive


Diffs (updated)
-----

  ql/src/java/org/apache/hadoop/hive/ql/io/parquet/read/DataWritableReadSupport.java d6be4bd

  ql/src/test/queries/clientpositive/parquet_join.q PRE-CREATION 

Diff: https://reviews.apache.org/r/24497/diff/


Testing
-------

parquet_join.q covers most types of joins between 2 parquet tables - Normal, Map join, SMB
join


Thanks,

Suma Shivaprasad
