Hi Charles, I have a query that sends a kvgen output to my UDF called MyUDF
like this,
select MyUDF(kvgen(convert_fromJSON(max(s.spark_event))['Spark Properties']))
In my UDF java code, I have defined the input parameter thus,
@Param
RepeatedMapHolder input;
How do I dereference this variable, I am using this line, It is throwing an
exception,
RepeatedMapHolder inputValue =
org.apache.drill.exec.expr.fn.impl.StringFunctionHelpers.toStringFromUTF8(input.start,
input.end, input.buffer);

Hi there,
Can you please either share your code, or provide us with more details with
what you are trying to do with your UDF?
Thanks,
