Consistency Check Failed (The configuration changes could not be validated for consistency due to an unknown error)

New Contributor

Hello, I've installed ambari kafka cluster with such configuration:

ambari_version: ''
hdp_version: ''
hdf_version: ''

on CentOS Linux release 7.8.2003 (Core)

However, when I'm trying to make some kafka configuration changes - I'm getting error message :



2020-09-14 18:03:06,088 ERROR [ambari-client-thread-471] ContainerResponse:423 - The exception contained within MappableContainerException could not be mapped to a response, re-throwing to the HTTP contai

Could you help me to understand where is the problem ?





Hi....i have a similar problem but havent found the root cause. Although, we do have a workaround in place. Please check this post :

The reason behind the error is that Ambari cannot fetch the recommended settings for the change. This can happen if the API call fails to receive any reply since the connection is blocked.


Hope this helps. If the comment helps you to find a solution or move forward, please accept it as a solution for other community members.
