> git.commit.id.abbrev=01bf849
> I have a hbase table that contains empty values for some columns/rows.   This was due
to importing data from a file into hbase. For example a get of a row containing empty age
value in hbase:
> hbase(main):003:0> get 'voterspaces', '17'
> COLUMN                       CELL                                                   
                         
>  fourcf:create_date          timestamp=1401380832939, value=2014-06-04 06:49:06     
                         
>  onecf:name                  timestamp=1401380832939, value=alice garcia

>  threecf:voterzone           timestamp=1401380832939, value=18555

>  twocf:registration          timestamp=1401380832939, value=republican       
> The following query from drill fails due to empty values instead of null:
> select cast(row_key as integer) voter_id, convert_from(onecf['name'], 'UTF8') 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 voterspaces where row_key < 20;
> message: "Failure while running fragment. < NumberFormatException:[  ]"
> From hive, running the same query against a hive table that is mapped to the same hbase
table succeeded.   If this how it expected to work in drill, then we should to document it.
