-------------------------------
git.commit.id.abbrev=8c66525
Ran the same query:
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;
Fails with the following error:
Query failed: Failure while running fragment.

> Select against hbase tables with empty number values fails

> Key: DRILL-862
> URL: https://issues.apache.org/jira/browse/DRILL-862
> Project: Apache Drill
> Issue Type: Bug
> Components: Storage - HBase
> Reporter: Krystal
> Assignee: Suresh Ollala
> Fix For: 0.5.0
>
>
> 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:contributions timestamp=1401380832939, value=468.51
>
> threecf:voterzone timestamp=1401380832939, value=18555
>
> twocf:age timestamp=1401380832939, value=
>
> 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.
