Review request for hive.


Fixed review comments

Bugs: HIVE-7629

Repository: hive-git


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/ d6be4bd

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



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