Hi,
I'm currently running Cloudera Manager 5.0.2. I am having problem when I try to delete host. And also when I try to assign roles to host.
I added 2 hosts into cluster:
1. Host 1 did not pass host inspection because I installed the wrong CDH version (5.1.2); other hosts are running CDH 5.0.3.
2. Host 2 installed successfully, but I run into error when I try to add role.
The error message is different, but I feel that the 2 problems are related somehow.
Here's the error log that I received when I try to delete host:

I've solved this issue.
Cloudera Embedded DB cannot write because it is located in my /var directory (under /var/lib/cloudera-scm-server-db) which is full. I use this step-by-step solution (credits to puneethabm from google group):

I tried to stop the cluster as you suggested via Cloudera Manager, I got the following error:
