View solution in original post
Yes, We can take NN & DN Configurations backup
/etc/hadoop/conf --for hadoop configuration files
/usr/hdp/126.96.36.199-3485 --ref for all the jars like sqoop jars etc
just it ?? I dont need anything else from HDP?? and for the centos OS??
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
I hope this will help:)
