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).
[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_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. 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 3.3.0.0-<build-no>
[root@host ~]# hdf-select set registry 3.3.0.0-<build-no>
[root@host ~]# hdf-select set streamline 3.3.0.0-<build-no>
[root@host ~]# hdf-select set storm-nimbus 3.3.0.0-<build-no>
[root@host ~]# hdf-select set storm-supervisor 3.3.0.0-<build-no>
[root@host ~]# hdf-select set zookeeper-client 3.3.0.0-<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 3.3.0.0-<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 the HDF
components that were updated.
[root@host ~]# hdf-select status | grep 3.3.0.0-<build-no>
nifi - 3.3.0.0-<build-no>
registry - 3.3.0.0-<build-no>
storm-nimbus - 3.3.0.0-<build-no>
storm-supervisor - 3.2.0.0-<build-no>
streamline - 3.3.0.0-<build-no>
zookeeper-client - 3.3.0.0-<build-no>
zookeeper-server - 3.3.0.0-<build-no>
-
Log into Ambari and start NiFi, NiFi Registry, SAM and Schema Registry. Confirm
all applications started and pre-existing flows, topologies, and configurations
are available.
