Upgrade HDF services

Confirm that the NiFi components are installed along with version (3.1.0.0).

[root@host registry]# yum list installed | grep nifi
nifi_3_1_0_0_<build-no>.x86_64
nifi-registry_3_1_0_0_<build-no>.x86_6

Display the current version associated with each component. In the following example, 3.1.0.0 is current version.

[root@host registry]# hdf-select status | grep nifi
nifi - 3.1.0.0-<build-no>
nifi-registry - 3.1.0.0-<build-no>

Install binaries for the HDF services to which you want to upgrade.

See the HDF Release Notes for the repository information, including service version and build number.

[root@host ~]# yum install -y <service>_<version>_<build-number>*

For example:

[root@host ~]# yum install -y nifi_3_3_0_0_165*

	Note
	Only run the `yum install` command on Ambari Agent hosts where NiFi is already installed.

Use hdf-select to ensure appropriate links to new installed version.

[root@host ~]# hdf-select set nifi 3.3.0.0-<build-no>
[root@host ~]# hdf-select set nifi -registry 3.3.0.0-<build-no>

Confirm that hdf-select shows the new version for the HDF services you updated.

[root@host ~]# hdf-select status | grep 3.3.0.0
nifi - 3.3.0.0-<build-no>
nifi-registry - 3.3.0.0-<build-no>

Log into Ambari and start NiFi and NiFi Registry.

You may add Schema Registry or SAM to your cluster, as needed.
