Can't organize HA in YARN when using capacity scheduler (CDH 5.8.x)

[ Edited ]

I'm using YARN with CDH5.8.x.

 

When I use default fair-scheduler with High Availiability on resource manager, that was working.

However, when I set capacity scheduler, HA is not working anymore.

It shows 2 servers still working as resource manager, but no server is activated. Two servers all work as stand-by.

 

As result, node managers do not start by connection error.

 

Can anyone tell me that is possible using capacity scheduler with HA, please?

The scheduler selection shouldn't impact the HA functions, generally. Do you have a snippet of the errors observed, and do you see the RMs coming up normally (including its Web UIs) after the scheduler reconfiguration?
