Replicate Impala and Hive User Defined Functions (UDFs)

By default, for clusters where the version of CDH is 5.7 or higher, Impala and Hive UDFs are persisted in the Hive Metastore and are replicated automatically as part of Hive/Impala replications.

After a replication job has run, you can see the number of Impala and Hive UDFs that were replicated during the last run of the schedule on the Replication Policies page. You can also view the number of replicated UDFs on the Replication History page for previously-run replications.
