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

             Summary: Invalid function resolution when varchar type argument is passed to
stddev function.
                 Key: DRILL-1523
                 URL: https://issues.apache.org/jira/browse/DRILL-1523
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Venki Korukanti


Executing following query results in error in compiling the generated code in streaming agg
batch. It should throw error saying there is no "stddev" function implementation found for
varchar input. Implicit cast is applied to varchar, but the cast is castTinyInt which is also
seems to be wrong. 

{code}
select stddev(full_name) from cp.`employee.json`;
{code}

{code}
Query failed: Screen received stop request sent. Line 57, Column 26: "value" is neither a
method, a field, nor a member class of "org.apache.drill.exec.expr.holders.NullableVarCharHolder"

{code}
