HDP2.1.7 upgrade notes

For anyone interested, I went through the HDP2.1.7 upgrade yesterday in our QA hadoop cluster. (Formerly running HDP2.1.5, centos6, using ambari 1.6.1).

I didn’t have any issues. A couple notes on the process from:

http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.1.7/bk_releasenotes_hdp_2.1/content/ch_relnotes-hdp-2.1.7-upgrade-from-2.1.5.html

Step 1: fetching the HDP repo
wget -O /etc/yum.repos.d/HDP.repo http://public-repo-1.hortonworks.com/HDP/centos6/2.x/updates/2.1.7.0/hdp.repo

Step 3: Upgrade the stack on all Agent hosts
– The “yum upgrade {component list}…” didn’t upgrade all components (I believe it was because there’s a space missing in the command). The subsequent “yum upgrade” took care of it.

Step 4: Complete the Stack upgrade
The recommended command for centos6 was:
ambari-server upgradestack HDP-2.1 http://public-repo-1.hortonworks.com/HDP/redhat6/2.x/updates/2.1.7.0 redhat6

However, this didn’t work. I had to use:
ambari-server upgradestack HDP-2.1 http://public-repo-1.hortonworks.com/HDP/centos6/2.x/updates/2.1.7.0 redhat6
