sudo yum install ambari-agent fails on ambari host

[#1]

Can an ambari agent be installed alongside ambari server?

I have an ambari server running with agents. I want to add the server as another agent.

On the ambar-server:

sudo yum install ambari-agent

Fails with the following output:

ambari-2.6.1.0                                                                                                                                                    | 2.9 kB  00:00:00

@Leonardo Apolonio

We see the error as conflict between packages:

file /usr/lib/python2.6/site-packages from install of ambari-agent-2.6.1.0-143.x86_64 conflicts with file from package ambari-server-2.6.1.0-0.x86_64

.

This error indicates that you have AmbariServer package of version 2.6.1.0.0 but trying to install Ambari-Agent of version 2.6.1.0-143 (slightly higher). Which is causing the conflict.

.

Please check if you have duplicate ambari repos like (2.6.1.0-143 as well as 2.6.1.0.0 both) on the same host?

In that case remove the Old unwanted ambari repo from the mentioned dir and then perform a yum clean.

# grep baseurl /etc/yum.repos.d/*  | grep ambari

So can you please try this:

# yum clean all

.

Then retry the agent installation or try the "yum upgrade ambari-server" first and then upgrade the agent.

# sudo yum upgrade ambari-server 
# sudo yum upgrade ambari-agent

.
