Yes, We can take NN & DN Configurations backup

/etc/hadoop/conf --for hadoop configuration files

/usr/hdp/2.3.4.0-3485 --ref for all the jars like sqoop jars etc

Is NN OS RAID configured?if yes, then i don't think it's required any additional backup.

Just FYI on what we are doing:

1) Our Master Nodes(NN & RM) are RAID configured

2) Taking DB ( ambari,Hue,OOzie etc) backup regularly.

3) HDFS Data backup using Falcon/distcp/Snapshot

4) /etc/hadoop/conf

5) /usr/hdp/2.3.4.0-3485/

I hope this will help:)
