I managed to install cloudera manager. However, now that i want to install the other tools on a single node cluster with 8gb ram. after selecting the host through the web portal of cdh manager, the installation fails.
From the logs when i filter on the error i get the following
ERROR: relation "cm_version" does not exist
I dont know where is the issue. Somebody wrote it was due to low ram however, i have plenty of ram. I dont know where is the issue.
