This article shows how to upgrade Hortonworks Data Platform (HDP) deployment using Ambari 2.2 when Isilon OneFS is used as the data storage for HDFS.
This guide applies to OneFS 220.127.116.11 or higher, OneFS 18.104.22.168 or higher, and later releases of OneFS.
There are two previous articles on this topic. One describes how to upgrade HDP, which required manual changes to work. Use that guide if you are using OneFS 22.214.171.124 or lower. OneFS was subsequently updated, making the process much easier. Use the later guide if you are not yet on OneFS 126.96.36.199 or 188.8.131.52, or if you are not ready to upgrade to Ambari 2.2.The following table shows all the upgrade choices.
||2.2 or higher||Current page|
|7.2.1 family equal or greater than 184.108.40.206||2.1 family. But, not 2.1.2 because of JIRA 13414||January 2016 guide|
|220.127.116.11 (with patch) or 18.104.22.168||2.1 family||November 2015 guide|
|22.214.171.124 or 126.96.36.199||2.1.0||No upgrade possible to HDP 2.3|
OneFS must report to the Ambari Server that it is at the target version. This is the 4-number release version and 4 digit build number of HDP. An example version is 188.8.131.52-2557. Determine version from the release notes of the HDP build that you are upgrading to, or by running the command 'hadoop version' on an existing deployment.
Use the following command to make the change on OneFS:
isi hdfs settings modify --odp-version=[version] --zone=[zone]
Begin Ambari's upgrade steps and complete installation of packages. Click the Perform Upgrade button. (If the button changed to a link named Upgrade: In Process, click on that.)
The Upgrade Options box opens:
No special instructions are needed for HDP upgrade using Express Upgrade with OneFS in the cluster. You may encounter the warning about the HDFS components not having version stamps, but you can ignore that warning.Proceed through the HDP upgrade wizard until the "Upgrade finished" dialog appears.
