Summary: Cast string to timestamp fails with split hbase table

Issue Type: Bug
Components: Storage - HBase
Reporter: Krystal

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 03:41:54
onecf:name timestamp=1400799413902, value=nick miller
threecf:contributions timestamp=1400799413902, value=717.12
threecf:voterzone timestamp=1400799413902, value=13809
twocf:age timestamp=1400799413902, value=68
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;
