Soren,
Can you give the complete stack trace? Or share the code? Perhaps, the
skeletal code.
Look at Ceil UDF for example, it has a null check, you should be able to do
something similar:
https://github.com/apache/hive/blob/trunk/ql/src/java/org/apache/hadoop/hive/ql/udf/UDFCeil.java#L43
I would e
Thanks. Did you mean I should handle null in my udf or my serde?
I did try to check for null inside the code in my udf, but it fails even
before it gets called.
This is from when the udf fails:
Caused by: org.apache.hadoop.hive.ql.metadata.HiveException: Unable to
execute method public o
There is no null argument. You should handle the null case in your code.
If (arga == null)
Or optionally you could use a generic udf but a regular one should handle
what you are doing.

Hi Hive community
I have a custom udf, say myfun, written in Java which I utilize like this
select myfun(col_a, col_b) from mytable where etc
col_b is a string type and sometimes it is null.
When that happens, my query crashes with
