Instead of rolling restarts, this will stop all services, and start them one at a time, with all hosts starting in parallel/batches. > Benefits: > * Relaxes requirements since NameNode HA is not needed > * Faster since, > ** Can upgrade an entire component by parallelizing across hosts. E.g., all ZK servers at once > ** Parallelize across components. E.g., Falcon Server and Storm Nimbus servers in parallel -- This message was sent by Atlassian JIRA (v6.3.4#6332)
