I have a CDH 5.1 cluster with 3 nodes. We installed it using cloudera manager automated installation. It was running perfect until we moved the box to a different network and IP addresses changed. I tried following steps

1. Stopped service, cloudera-scm-server.
2. Stopped service, cloudera-scm-agent
3. Edit the /etc/cloudera-scm-agent/config.ini
4. change the server host to the new ip.
5. restart service, cloudera-scm-agent, cloudera-scm-server.

not working .

Then i followed http://www.cloudera.com/content/cloudera/en/documentation/cloudera-manager/v4-latest/Cloudera-Manage... Not helped even after changing the ips in the PostgreSQL directly.

I found following blog : http://www.geovanie.me/changing-ip-of-node-in-cdh-cluster/

Getting following error in the scm-agent log file

ProtocolError: <ProtocolError for 127.0.0.1/RPC2: 401 Unauthorized>

No helped .... Can anyone please help how to change all IP addresses in a cdh 5.1 cluster safely .....

Thanks, Amit
