How to update the IP adress of a node on CDH 6.2?

[#1]

I simply set a new IP address to the server in my cluster by setting the DHCP in my router.

But, after restart the cluster, CDH is still connecting the old IP address, so that it can't get connected.

So, where can I update the IP address?

Check if new IP got updated in hdfs-site.xml and core-site.xml. Also, try clearing nscd cache in all the nodes and restart CDH cluster, CM agent and CM services.

Thanks a lot, I take a try.
