Upgrade HDF services
Ensure that you complete these steps on each node that contains an HDF service.
Ensure that you have backed up your SAM and Schema Registry
databases.
-
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
-
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
-
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*
NoteOnly run theyum 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 3.4.1.1-4 [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
-
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
- 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.
