Before You Install
Before you begin a production installation of Cloudera Manager, Cloudera Runtime, and other managed services, review the Cloudera Private Cloud Base Requirements and Supported Versions, in addition to the Cloudera Data Platform Release Notes.
For planning, best practices, and recommendations, review the CDP Private Cloud Base Reference Architecture.
YARN Queue Manager in Cloudera Data Platform (CDP) Private Cloud Base 7.1.9 CHF 2 does not
require you to install a PostGres database, therefore users should not see the Setup Database
screen and should be able to skip the Setup Database screen. When conducting a fresh install
of 7.1.9 CHF 2, and if you are unable to bypass the Setup Database screen, perform the
following steps:
- Ensure that you have both CDP and Cloudera Manager upgraded to 7.1.9 CHF 2.
- When you reach the Setup Database screen in the Cloudera Manager installation wizard for
Queue Manager, enter any dummy values for the following fields:
- Database name: configstore
- Database Username: dbuser
- Database Password: dbpassword
- Database Hostname: localhost
- Run the following script command in a browser console to enable the
Continue button:
document.querySelector('.btn.next').removeAttribute('disabled'); - Click Continue and proceed with the YARN Queue Manager installation.
- After installation is complete, SSH into the host that has Queue Manager installed, and
run this command:
sed -i 's/migrationCompleted=true/migrationCompleted=false/' /var/lib/hadoop-yarn/migration.properties - Restart YARN Queue Manager.
The following topics describe additional considerations you should be aware of before beginning an installation:
