Replication of 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.

To replicate Impala UDFs when the version of CDH managed by Cloudera Manager is 5.6 or lower, see for information on when to select the Replicate Impala Metadata option on the Advanced tab when creating a Hive/Impala replication schedule.

After a replication 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 Schedules page:

For previously-run replications, the number of replicated UDFs displays on the Replication History page:
