Subject [jira] [Commented] (HIVE-1643) support range scans and non-key columns in HBase filter pushdown
Date Wed, 09 Jan 2013 10:25:38 GMT


Hudson commented on HIVE-1643:

Integrated in Hive-trunk-hadoop2 #54 (See [])
    HIVE-2771 [jira] Add support for filter pushdown for key ranges in hbase for
keys of type string
(Ashutosh Chauhan via Carl Steinbach)


This patch adds support for key range scans pushdown to hbase for keys of type
string. With this patch filter pushdowns of following types are supported:
a) Point lookups for keys of any types.
b) Range scans for keys of type string. 

Test Plan:
Added hbase_ppd_key_range.q which is modeled after hbase_pushdown.q

This is a subtask of HIVE-1643

Test Plan: EMPTY

> 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.
