Xuefu Zhang commented on HIVE-9410:
-----------------------------------
I think what [~vanzin] suggested above is incorporated in HIVE-11878, where a
new class, UDFClassLoader was introduced.
> ClassNotFoundException occurs during hive query case execution with UDF
> defined [Spark Branch]

> We have a hive query case with UDF defined (i.e. BigBench case Q10, Q18
> etc.). It will be passed for default Hive (on MR) mode, while failed for Hive
> On Spark mode (both Standalone and Yarn-Client).
> Although we use 'add jar XXXX.jar;' to add the UDF jar explicitly, the issue
> still exists.
> BTW, if we put the UDF jar into $HIVE_HOME/lib dir, the case will be passed.
> Detail Error Message is as below (NOTE:
> de.bankmark.bigbench.queries.q10.SentimentUDF is the UDF which contained in
> jar bigbenchqueriesmr.jar, and we have add command like 'add jar
> /location/to/bigbenchqueriesmr.jar;' into .sql explicitly)
