Check Prerequisites	Onboard new users	Check for zombie jobs	Reevaluate node and volume topology	Perform security audit
Verify Installation	Offboard users	Perform simple performance test	Check performance (jobs, I/O)	Upgrade core, Hive, HCatalog
High Availability planning	Check cluster health	Verify snapshots	Verify mirrors
Set up VIPs for NFS for the HPE Ezmeral Data Fabric	Perform hardware maintenance (disks)	Remove old snapshots	Clean up data
Benchmark and tuning		Failbacks to restore service layout	file system balancing
