Hi,

We were trying to enable TLS on our cluster.We have followed cloudera steps ,but i think missed something.After enabling TLS,we were able to login to port 7183,but all  cloudera management services were disabled.

 

So we reverted back TLS changes from cloudera and removed all keys and certificates.After that given restart to the cloudera manager.

 

After this process,port 7180 started and login page came.But when i am trying to login then it is not redirecting to the GUI.

when i have check the logs. then these exceptions are showing.

@pdev have you disabled TLS in the management services as well? After you disable/enable TLS, you will have restart the management services so they communicate with CM with the changed port and protocol.

Hi Rajesh,

We have disabled tls from cloudera admin and removed truststore path and password from cloudera management services.

I hope this what you are asking.if not then please share steps to disable it.

 

Thanks.
