Ambari Agent Not Starting

bkandalkar — Wed, 18 Jul 2018 19:58:38 GMT

Hi,

We are using Ambari server 2.6.2 and Ambari agent 2.6.2. We are using Ubuntu 14.04 LTS.

We have upgraded Python version from Python-2.7.6 to Python-2.7.9 on Ambari server and Ambari Agent.

After starting Ambari server and Ambari agent, in Ambari server log we got following error:

Ambari agent is not starting due above error.

How to resolve it? We need Python-2.7.9 in our cluster.

Please suggest.

Thanks in advance.

@Bhushan Kandalkar

It seems the OS type is not supported. Agent os type: debianjessie/sid

@Sandeep Nemuri, on Python 2.7.6 all agents are able to communicate with Ambari server. But when we upgrade Python to Python 2.7.9 we get this OS error. Could you please suggest why we are getting error after upgrading to Python 2.7.9?

@Bhushan Kandalkar So the issue is with how python returns the os name. You can see the full details in this SO thread. If you want a new python version you can use anaconda and install the python in another path and leave the default one as it is.

Thanks @Sandeep Nemuri. We have resolved OS issue by applying patch mentioned in SO thread.
