Description

git commit # : 9878170d082a58af08b0b7b75494a76546d73580

The below queries succeed :

 select min(columns[0]) from dfs.`/drill/testdata/lineitem.tbl`;
select abs(columns[0] + 1) from dfs.`/drill/testdata/lineitem.tbl`;

However the below query fails

select abs(columns[0]) from dfs.`/drill/testdata/lineitem.tbl`;
Error: SYSTEM ERROR: SchemaChangeException: Failure while trying to materialize incoming schema.  Errors:
 
Error in expression at index -1.  Error: Missing function implementation: [castTINYINT(VARCHAR-OPTIONAL)].  Full expression: --UNKNOWN EXPRESSION--..

Any reason why implicit casting is not working in the above case? I attached the logs and the data file.
