Oozie HA: When a node goes down

[ae...@orange.com]

Hi,

I want to understand some aspects about operating mode of Oozie HA:

When submitting a workflow to the load balancer, actions can be processed by many servers ?
If yes, when a server goes down, its actions will be executed on other server ? How others servers can know ths status of actions ?

regards,
Ahmed

Yes, Any server can execute workflow actions. Workflow and actions state are stored in the database.When one server executes action it update the action states in the database, other servers will read updated state from the database.

Oozie has inbuilt Recovery services. Which can recover jobs in case one of oozie server goes down.
 
Thanks,
