> The following query fails:
> {noformat}
> create table tb1 (year string, month string);
> create table tb2(month string);
> select unix_timestamp(a.year) 
> from (select * from tb1 where year='2001') a join tb2 b on (a.month=b.month);
> {noformat}
> with the exception {noformat}
> Caused by: java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
>         at java.util.ArrayList.rangeCheck(ArrayList.java:635)
>         at java.util.ArrayList.get(ArrayList.java:411)

>         at org.apache.hadoop.hive.ql.exec.CommonJoinOperator.getJoinOutputObjectInspector(CommonJoinOperator.java:175)
> {noformat}
> The issue seems to be: during the query compilation, the field in the select should be
replaced with the constant when some UDFs are used.
