FAQs About Upgrade

Sometimes, even after deleting mpacks, residual corrupted references may remain. As a result, stack versions might not appear during upgrades from versions 3.2.2.x, 3.2.3.0-x, 3.2.3.1-x, or 3.2.3.2-x. Starting from Ambari version 2.7.8.2-x (ODP-3.2.3.3-x) onwards, only 3.3 and 3.4 stack versions are listed.

How to get 3.3 and 3.4 stacks shown in the Ambari UI?

  1. Clone the Upgrade Utility Repository and navigate to the Upgrade Scripts Directory.
git clone https://github.com/acceldata-io/ce-utils.git

cd ce-utils/odp-upgrade-to-3.3.6.6/upgrade_files_336
  1. Copy the 3.3 directory into the below location on Ambari server node.
cp -r 3.3  /var/lib/ambari-server/resources/stacks/ODP/
  1. Validate the permission and ownership as below.
ls -lrth /var/lib/ambari-server/resources/stacks/ODP/

The response included with 3.3 stack.

drwxr-xr-x 7 root root  141 Apr 23 20:08 3.0
drwxr-xr-x 5 root root   71 Apr 23 20:08 3.1
drwxr-xr-x 5 root root  102 Apr 23 20:08 3.2
drwxr-xr-x 5 root root 4.0K Apr 24 16:23 3.3
  1. Copy the upgrade and nonrolling-upgrade.xml from /var/lib/ambari-server/resources/stacks/ODP/3.3/upgrades/ to /var/lib/ambari-server/resources/stacks/ODP/3.2/upgrades/.
cp /var/lib/ambari-server/resources/stacks/ODP/3.3/upgrades/nonrolling-upgrade-3.3.xml   /var/lib/ambari-server/resources/stacks/ODP/3.2/upgrades/
 
cp /var/lib/ambari-server/resources/stacks/ODP/3.3/upgrades/upgrade-3.3.xml  /var/lib/ambari-server/resources/stacks/ODP/3.2/upgrades/
  1. Change the permission to 755 for xmls copied in Step 4.
chmod 755 /var/lib/ambari-server/resources/stacks/ODP/3.2/upgrades/upgrade-3.3.xml
chmod 755 /var/lib/ambari-server/resources/stacks/ODP/3.2/upgrades/nonrolling-upgrade-3.3.xml
  1. Perform the Ambari-server restart step.
ambari-server restart

After restart, you can see the 3.3 stack in the Stack Versions page.
