----------------------------------------

             Summary: convert_from should throw an appropriate error when an invalid data
type is used as the second argument
                 Key: DRILL-2609
                 URL: https://issues.apache.org/jira/browse/DRILL-2609
             Project: Apache Drill
          Issue Type: Bug
          Components: Storage - HBase

            Assignee: Aditya Kishore

git.commit.id.abbrev=4d398ed

The below query fails with an assertion error. It would be nice if it returns a proper error
message indicating that the datatype used is invalid
{code}
0: jdbc:drill:schema=dfs.hbase> select convert_from(a.types.int_col, 'abc') from hbase.fewtypes_null
a;
Query failed: AssertionError:
{code}

Below is the error from the logs :
{code}
