Subject Re: Showing INFO ipc.Client: Retrying connect to server once hadoop is upgraded to cdh5.2.0
Date Mon, 24 Nov 2014 05:04:46 GMT
I had this problem on a small cluster running Debian, in my case the 
issue was caused by a reference to 0.0.0.0 as localhost in /etc/hosts, I 
removed it leaving just 127.0.0.1 as localhost ip and the problem was 
solved. If it's not the same issue it could be something similar about 
address resolution... try to understand if this only happens between the 
same source and destination.

Regards

Fabio
