Bugs: DRILL-571
https://issues.apache.org/jira/browse/DRILL-571
Repository: drill-git
Description
-------
This patch adds an Optimizer rule to HBase storage plugin which would transform
an HBase scan followed by a logical (==, !=, <, <=, >, >=) filter on the row
key into an HBase scan with filter thus minimizing the data transfer and
elimination one operation altogether.

Testing
-------
Added a new test case TestHBaseFilterPushDown which is currently disabled since
the Zookeeper port used by MiniHBase cluster is random and there was no clean
way to pass this to the HBase storage plugin from SQL.
To test it, start a local HBase cluster (./bin/start-hbase.sh) and un-comment
the Junit's @Ignore annotation.
Thanks,
Aditya Kishore
