> 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" [96d9040e-a5ae-41b4-a409-36933817b8ef]
