If you are upgrading HDF services installed on an HDP cluster, you must stop HDF
services before you upgrade Ambari, HDP, and HDF.
- This step is necessary whether or not you are upgrading Ambari.
- This step is not necessary if you are upgrading an HDF-only cluster.
-
Identify the HDF services you have running. They are:
- NiFi
- NiFi Registry
- Schema Registry
- Streaming Analytics Manager
-
Stop the service from Ambari Web, by browsing to Services
>
hdf-service-name and select Stop from
the Service Actions menu. Then select Turn on
Maintenance Mode.
Replace hdf-service-name with each of the HDF services you
have running.
