-------------------------------------
Summary: Cast of non-existent column results in UnsupportedOperation exception
Key: DRILL-482
URL: https://issues.apache.org/jira/browse/DRILL-482

For example, this query:
select cast(name as varchar(10)) from cp.`tpch/nation.parquet`;
the column name does not exist.
here is the stack trace.
java.lang.UnsupportedOperationException: FunctionCall is not expected here. It should have been converted to FunctionHolderExpression in materialization
