Subject [jira] [Updated] (HIVE-1643) support range scans and non-key columns in HBase filter pushdown

     [ https://issues.apache.org/jira/browse/HIVE-1643?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Sandy Pratt updated HIVE-1643:
------------------------------

    Attachment: hbase_handler.patch

A patch I am currently testing, which allows a single equals predicate on the rowkey or a
single or double ended range scan to be passed to the HBase layer.

> HIVE-1226 added support for WHERE rowkey=3.  We would like to support WHERE rowkey BETWEEN
10 and 20, as well as predicates on non-rowkeys (plus conjunctions etc).  Non-rowkey conditions
can't be used to filter out entire ranges, but they can be used to push the per-row filter
processing as far down as possible.
