> I have a split hbase table. Here is one record in the table:
> hbase(main):004:0> get 'voter', '1'
> COLUMN CELL

> fourcf:create_date timestamp=1400799413902, value=2014-05-25

> twocf:registration timestamp=1400799413902, value=green

> 6 row(s) in 0.4660 seconds
> The following sql query against this table failed.
> 0: jdbc:drill:schema=hbase> select date_add(cast(fourcf['create_date'] as
> timestamp), interval '3' hour) from voter where row_key=5;
> message: "Failure while running fragment. < UnsupportedOperationException:[
> CastExpression is not expected here. It should have been converted to
> FunctionHolderExpression in materialization ]"
> The same query runs fine against a table without split:
> 0: jdbc:drill:schema=hbase> select date_add(cast(fourcf['create_date'] as
> timestamp), interval '3' hour) from s_voter where row_key=5;
