@Sunile Manjee

HA is only related to Oozie server, which is stateless (rely on its backend database).

Since, failover can only be seen from a job submission perspective so there's no impact on current running jobs.

@Laurent Edel what about the jobs are planified to be run? if every oozie server know that there are jobs that must be executed, how to decide which execute the job? If it is done by locking using zookeeper, it does the job submissionpasses trhoughtout the load balancer /dns round robin / VIP?
