[#1]

I am trying to use python udf in hive, but i get the below error

Error: Error while processing statement: FAILED: Hive Internal Error: org.apache.hadoop.hive.ql.security.authorization.plugin.HiveAccessControlException(Query with transform clause is disallowed in current configuration.) (state=08S01,code=12)
