Non rowkey predicate pushdown in Hive-HBase handler (Hive jira - 1643)

by bharath v for Apache Software Foundation

This project aims at optimizing the network IO in Hive queries on HBase StorageHandler by converting non-row-key predicates into corresponding HBase filters and pushing them down in the query tree and using row-key predicates to determine scan ranges.
