Deployment of Cloudera Enterprise (CDH) 5.4.4 can be implemented directly on Microsoft Azure Virtual Machines and we can start working on Impala shell & Hue itself.
The hosting process is super easy, you just need to make sure the following prerequisites & troubleshooting steps should be taken care off.
Prerequisites: SELinux should be disabled. Before disabling SELinux you may try sysctl -w vm.swappiness=0.
You have to add the line below in /etc/sysctl.conf to keep your change permanently:
vm.swappiness = 10
- Change the root password
- Change the hostname in /etc/hosts file
- Add ports 7180, 7182, 9000, 9001 open
- Passwordless sudo user authentication
- Change the /etc/hosts file , the hostname from hosts IP address by $ifconfig
Issue: Cloudera Manager site is not opening on browser after installation & the following error shows on log. cloudera-scm-server dead but pid file exists
Follow these steps:
# service cloudera-scm-server stop
# service cloudera-scm-server-db stop
# rm /var/run/cloudera-scm-server.pid
# service cloudera-scm-server-db start
# service cloudera-scm-server start
