Gézapeti commented on OOZIE-3572:
---------------------------------
I think Oozie should be able to run actions in a single workflow in different
Yarn clusters.
I'm quite confident that it works as well. I haven't tried it, but action
configs are loaded according to the ResourceManager defined for that action,
based ont the {{oozie.service.HadoopAccessorService.hadoop.configurations}}
you've mentioned.
The actions can only work on the same HDFS however as the HDFS tokens are only
grabbed for the workflow.xml's location. OOZIE-3575 can address this by
introducing the FS credentials. I don't know much about HDFS federation, we
might have bugs around that in the token handling.

> Project: Oozie
> Issue Type: Improvement
> Reporter: Junfan Zhang
> Priority: Major
>
> Currently in our production environment, there are more than 10 clusters, and
> each cluster is deployed with Oozie server. This has caused difficulties in
> operation and maintenance, and difficulty in expanding the workflow between
> multiple clusters.
> Does the community have plans to support actions running in different
> clusters?
> Or give me some suggestions
