[jira] [Created] (DRILL-3234) Drill fails to implicit cast hive tinyint and smallint data as int

Krystal created DRILL-3234:
------------------------------

             Summary: Drill fails to implicit cast hive tinyint and smallint data as int
                 Key: DRILL-3234
                 URL: https://issues.apache.org/jira/browse/DRILL-3234
             Project: Apache Drill
          Issue Type: Bug
          Components: Storage - Hive
    Affects Versions: 1.0.0
            Reporter: Krystal
            Assignee: Venki Korukanti


I have the following hive table:
 describe `hive.default`.voter_hive;
+----------------+------------+--------------+
|  COLUMN_NAME   | DATA_TYPE  | IS_NULLABLE  |
+----------------+------------+--------------+
| voter_id       | SMALLINT   | YES          |
| name           | VARCHAR    | YES          |
| age            | TINYINT    | YES          |
| registration   | VARCHAR    | YES          |
| contributions  | DECIMAL    | YES          |
| voterzone      | INTEGER    | YES          |
| create_time    | TIMESTAMP  | YES          |
+----------------+------------+--------------+

If just include the voter_id and age fields in the select, then the query works fine.  However if I include them in the where clause, the query would fail. For example:

select voter_id, name, age from voter_hive where age < 30;
Error: SYSTEM ERROR: org.apache.drill.exec.exception.SchemaChangeException: Failure while trying to materialize incoming schema.  Errors:
 
Error in expression at index -1.  Error: Missing function implementation: [castINT(TINYINT-OPTIONAL)].  Full expression: --UNKNOWN EXPRESSION--..
