Upgrade HDF services

Confirm HDF components installed along with version (e.g. 3.0.2.0-76).

[root@host registry]# yum list installed | grep HDF

hdf-select.noarch                 3.0.2.0-76.el6           @HDF-3.0            
nifi_3_0_2_0_76.x86_64           1.2.0.3.0.2.0-76.el6     @HDF-3.0            
                                  0.7.0.3.0.2.0-76.el6     @HDF-3.0            
registry_3_0_2_0_76.noarch       0.3.0.3.0.2.0-76.el6     @HDF-3.0            
storm__3_0_2_0_76.x86_64          1.1.0.3.0.2.0-76.el6     @HDF-3.0            
streamline_3_0_2_0_76.x86_64     0.5.0.3.0.2.0-76.el6     @HDF-3.0            
zookeeper_3_0_2_0_76.noarch      3.4.6.3.0.2.0-76.el6     @HDF-3.0

Display the current version associated with each component (in following example 3.0.2.0-76 is current version).

[root@host registry]# hdf-select status | grep 3.0.2.0-76

nifi - 3.0.2.0-76
registry - 3.0.2.0-76
storm-client - 3.0.2.0-76
storm-nimbus - 3.0.2.0-76
storm-supervisor - 3.0.2.0-76
streamline - 3.0.2.0-76
zookeeper-client - 3.0.2.0-76
zookeeper-server - 3.0.2.0-76

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_2_0_0_520*

	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. Note that SAM also brings down Storm and ZooKeeper dependencies that also needs to be accounted for.

For example,

[root@host ~]# hdf-select set nifi 3.2.0.0-<build-no>
[root@host ~]# hdf-select set registry 3.2.0.0-<build-no>
[root@host ~]# hdf-select set streamline 3.2.0.0-<build-no>
[root@host ~]# hdf-select set storm-nimbus 3.2.0.0-<build-no>
[root@host ~]# hdf-select set storm-supervisor 3.2.0.0-<build-no>
[root@host ~]# hdf-select set zookeeper-client 3.2.0.0-<build-no>

WARNING: Replacing link /usr/bin/zookeeper-client from /usr/hdp/current/zookeeper-client/bin/zookeeper-client

[root@host ~]# hdf-select set zookeeper-server 3.2.0.0-<build-no>

WARNING: Replacing link /usr/bin/zookeeper-server from /usr/hdp/current/zookeeper-server/bin/zookeeper-server
WARNING: Replacing link /usr/bin/zookeeper-server-cleanup from /usr/hdp/current/zookeeper-server/bin/zookeeper-server-cleanup

Confirm that hdf select shows new version for hdf components that were updated.

[root@host ~]# hdf-select status | grep 3.2.0.0-<build-no>
nifi - 3.2.0.0-<build-no>
registry - 3.2.0.0-<build-no>
storm-nimbus - 3.2.0.0-<build-no>
storm-supervisor - 3.2.0.0-<build-no>
streamline - 3.2.0.0-<build-no>
zookeeper-client - 3.2.0.0-<build-no>
zookeeper-server - 3.2.0.0-<build-no>

Log into Ambari and start NiFi, NiFi Registry, SAM and Schema Registry. Confirm all applications started and pre-existing flows/topologies/configurations are available.
