Upgrade HDF services

Ensure that you complete these steps on each node that contains an HDF service.

1. Confirm HDF components installed along with version (e.g. 3.2.0.0-520).

   For example:

   [root@host registry]# yum list installed | grep HDF
   
   hdf-select.noarch                 3.2.0.0-520.el6           @HDF-3.2            
   nifi_3_2_0_0_520.x86_64           1.7.0.3.2.0.0-520.el6     @HDF-3.2            
                                     0.7.0.3.2.0.0-520.el6     @HDF-3.2            
   registry_3_2_0_0_520.noarch       0.5.3.3.2.0.0-520.el6     @HDF-3.2           
   storm__3_0_2_0_76.x86_64          1.2.1.3.2.0.0-520.el6     @HDF-3.2            
   streamline_3_0_2_0_76.x86_64      0.6.0.3.2.0.0-520.el6     @HDF-3.2           
   zookeeper_3_0_2_0_76.noarch       3.4.6.3.2.0.0-520.el6     @HDF-3.2         
   

2. Display the current version associated with each component.

   [root@host registry]# hdf-select status | grep 3.2.0.0-520
   
   nifi - 3.2.0.0-520
   registry - 3.2.0.0-520
   storm-client - 3.2.0.0-520
   storm-nimbus - 3.2.0.0-520
   storm-supervisor - 3.2.0.0-520
   streamline - 3.2.0.0-520
   zookeeper-client - 3.2.0.0-520
   zookeeper-server - 3.2.0.0-520
   

3. 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_4_1_1_4*

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

4. 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 3.4.1.1-4
   [root@host ~]# hdf-select set registry 3.4.1.1-4
   [root@host ~]# hdf-select set streamline 3.4.1.1-4
   [root@host ~]# hdf-select set storm-nimbus 3.4.1.1-4
   [root@host ~]# hdf-select set storm-supervisor 3.4.1.1-4
   [root@host ~]# hdf-select set zookeeper-client 3.4.1.1-4
   
   WARNING: Replacing link /usr/bin/zookeeper-client from /usr/hdp/current/zookeeper-client/bin/zookeeper-client
   
   [root@host ~]# hdf-select set zookeeper-server 3.4.1.1-4
   
   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
   

5. Confirm that hdf-select shows new version for the HDF components that were updated.

   [root@host ~]# hdf-select status | grep 3.4.1.1-4
   nifi - 3.4.1.1-4
   registry - 3.4.1.1-4
   storm-nimbus - 3.4.1.1-4
   storm-supervisor - 3.4.1.1-4
   streamline - 3.4.1.1-4
   zookeeper-client - 3.4.1.1-4
   zookeeper-server - 3.4.1.1-4
   

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