IP chaged for Hadoop cluster, what all needs to check?

Vishaljain000 — Fri, 24 Jun 2016 18:26:06 GMT

HI,

We have moved our Horthonworks hadoop cluster to new VLAN, so I am curious on what all config I need to validate that cluster is healthy & working with the new IP?

FYI... I can login to Ambari UI through new IP url & I can see old IPs in Ambari host details.

Thanks.

Regards,

Vishal

It should be okay as your hostnames are getting resolved to new IP address. Please run service checks from Ambari UI for important HDP components to see if everything is working fine.
