Added more changes. Please review.
Bugs: HIVE-8359
https://issues.apache.org/jira/browse/HIVE-8359
Repository: hive-git
Description
-------
The patch changes the way DataWritableWriter class writes an array of elements
to the Parquet record.
It wraps each array record into a new startGroup/endGroup block so that Parquet
can detect null values on those optional fields.
