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
