Cloudera Manager fails to add hosts

Question

I\'ve followed the installation procedure from here and when I reach the Inspect Role Assignments stage I only see one managed host: localhost.localdo

Answer 1

To solve this error, I did three things:

1) vim /etc/cloudera-scm-agent/config.ini Originally it was

# Hostname of Cloudera SCM Server
   server_host=localhost

Changed hostname to:

server_host=manager

Also make sure the 'manager' is added in the /etc/hosts file

2) Installed java in the /usr/local/java/jdk1.7xxx directory In ~/.bash_profile Included following

export JAVA_HOME=/usr/local/java/jdk1.7xxx

Soft Link can also be used for this purpose:

export PATH=$PATH:$JAVA_HOME:bin

Cloudera probably takes the java path as '/usr/java'. So I created a symbolic link in the /usr directory.

3) When it still did not work, I installed MySQL Connector using the following:

yum install mysql-connector-java

Restart server and restart agents. It worked for me then.
