Alexander Pivovarov commented on HIVE-9857:
-------------------------------------------
This UDF uses one of the common-math3 class.
I checked all jars in hive/lib folder. common-math3 packages are found in
hive/lib/hive-jdbc-1.2.0-SNAPSHOT-standalone.jar only.
There is a JIRA HIVE-9599 to remove all irrelevant for jdbc driver classes from
hive-jdbc-standalone.
HIVE-9599.2.patch excludes common-math3 from standalone jar
Probably we should explicitly add common-math3 dependency to hive.
Currently hive-exec has transitive compile time dependency to
common-math3-3.1.1 from spark-core
I'm not sure what common-math3 version should I add to hive pom.xml. The latest
3.4.1 or 3.1.1 to avoid potential conflicts with spark-core.
