separation of JVMs for different applications

Manu Zhang
Hi all,

It seems tasks of different Flink applications can end up in the same JVM
(TaskManager) in standalone mode. Isn't this fragile since errors in one
application could crash another ? I checked FLIP-6
<https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=65147077> but
didn't found any mention of changing it in the future.

Any thoughts or have I missed anything ?

Thanks,
Manu Zhang

Hi Manu,

As far as I know, there are not plans to change the stand-alone deployment.
FLIP-6 is focusing on deployments via resource providers (YARN, Mesos,
etc.) which allow to start Flink processes per job.

Till (in CC) is more familiar with the FLIP-6 effort and might be able to
add more detail.

Best,
Fabian
