Cloudera Manager installation Distribution is failling

Cloudera Manager installation Distribution is failling

Contributor

Hi,

I am instaling a new cluster with the latetest version of cloudera. 

In the /cmf/express-wizard/ I am adding my current machine as a client. 

The parcels get downloaded but never distributed.

in the logs I have something like :

@Jayaprakash,

 

Please post the agent log so we can review and verify you are seeing exactly the same stack trace.

Since this thread is old, it is better to start a new one and post your own story and data.

Add some screen shots where it is easier to show than tell.

 

Cheers,

 

Ben

Both commands show that it is trying over IPv6 first and then by IP. The former fails with a connection refused while the latter succeeds. I would disable IPv6 on all hosts but for this it can just be the CM host, and then try again.
