I can still reproduce the problem.  Maybe because of my dataset?  Attached is the data I used
for this test.  I created the table in hbase as follows:
create 'voter', 'onecf', 'twocf', 'threecf', 'fourcf', {SPLITS => ['1','2','3','4','5','6','7','8','9']}
I used pig to load the data into table voter:
register /opt/mapr/hbase/hbase-0.94.17/lib/zookeeper-3.4.5-mapr-1401.jar;
register /opt/mapr/hbase/hbase-0.94.17/hbase-0.94.17-mapr-1403-SNAPSHOT.jar;
register /opt/mapr/hbase/hbase-0.94.17/lib/guava-11.0.2.jar;

A = LOAD '/drill/testdata/hbase/votertab' AS (id,name,age,registration,contributions,voterzone,create_date);
STORE A INTO 'voter' USING org.apache.pig.backend.hadoop.hbase.HBaseStorage('onecf:name twocf:age
twocf:registration threecf:contributions threecf:voterzone fourcf:create_date');

> This is a regression. Ran the following query in sqlline:
> 0: jdbc:drill:schema=dfs> select cast(row_key as integer) voter_id, cast(onecf['name']
as varchar(30)) name, cast(twocf['age'] as integer) age, cast(twocf['registration'] as varchar(20))
registration, cast(threecf['contributions'] as decimal(6,2)) contributions, cast(threecf['voterzone']
as integer) voterzone,cast(fourcf['create_date'] as timestamp) create_date from hbase.voter
where row_key = 5;
> +------------+------------+------------+--------------+---------------+------------+-------------+
> |  voter_id  |    name    |    age     | registration | contributions | voterzone  |
create_date |
> +------------+------------+------------+--------------+---------------+------------+-------------+
> | 5          | null       | null       | null         | null          | null       |

> +------------+------------+------------+--------------+---------------+------------+-------------+
> The same query returns expected data against an hbase table that resides in single partition.
