> I created jar file which overloads 3 DRILL native functions (LOG(VARCHAR-REQUIRED), CURRENT_DATE(VARCHAR-REQUIRED)
and ABS(VARCHAR-REQUIRED,VARCHAR-REQUIRED)) and registered it as dynamic UDF.
> If I try to use my functions I will get errors:
> {code:xml}
> SELECT CURRENT_DATE('test') FROM (VALUES(1));
> {code}
> Error: FUNCTION ERROR: CURRENT_DATE does not support operand types (CHAR)
> SQL Query null
> {code:xml}
> SELECT ABS('test','test') FROM (VALUES(1));
> {code}
> Error: FUNCTION ERROR: ABS does not support operand types (CHAR,CHAR)
> SQL Query null
> {code:xml}
> SELECT LOG('test') FROM (VALUES(1));
> {code}
> Error: SYSTEM ERROR: DrillRuntimeException: Failure while materializing expression in
constant expression evaluator LOG('test').  Errors: 
> Error in expression at index -1.  Error: Missing function implementation: castTINYINT(VARCHAR-REQUIRED).
 Full expression: UNKNOWN EXPRESSION.
> But if I rerun all this queries after "DrillRuntimeException", they will run correctly.
It seems that Drill have not updated the function signature before that error. Also if I add
jar as usual UDF (copy jar to /drill_home/jars/3rdparty and restart drillbits), all queries
will run correctly without errors.
