Unable to restart kafka broker

[#1]

Hi All,

I am trying to restart one of my kafka broker for stale configuration due to ranger configuration changes.

However, one of the kafka broker is not coming up and is not throwing any error as well. I reverted back the ranger configuration but to no avail. The only error that i see is the below error in the ambari stderr output:

Traceback (most recent call last):

Hi @Aditya Gopal:

It looks like the version of python on this node has been changed to one where the method called is not available. Has there been a change or upgrade to the version of python installed on this particular node recently?

Thank you,
