PHD 1.1.X to PHD2.0.X upgrade using ICM
After the PHD upgrade, only default queue is available with capacity scheduler.
To list the available queues, run the following command:
hadoop queue -list
During upgrade, ICM pushes the configurations available under the cluster configuration directory, if capacity-scheduler.xml file configured with queues was not used to reconfigure, then default capacity-scheduler.xml file is pushed to the nodes and user loses the configured queues.
1: You should still have a backup of capacity-scheduler.xml if you did fetch-configuration before upgrading. We assume that icm_client reconfigure was used to push capacity-scheduler.xml to all the nodes earlier. In case, backup of capacity-scheduler.xml is not available, please follow this article to manually add the queues again.
2: Modify the original capacity-scheduler.xml by updating
3: After updating capacity-scheduler.xml, use icm_client reconfigure to push the updated capacity-scheduler.xml file to the cluster nodes.
