Tobin Baker commented on YARN-3928:
-----------------------------------
We really need this for our application, and having to use node labels instead
is a very awkward workaround (it can't be done programmatically from our YARN
client, which runs with limited privileges). Instead, we make administrators
manually configure the node label that the AM runs on, rather than have the
application specify the AM location automatically.

> Hi,
> Is there a way to launch application master on a specific host ?
> If we can not do this in a managed-AM-launcher?
> then is it possible to achieve this in unmanaged-AM-launcher?
> I just find it's quite necessary to set application master on a specific host
> in some scenes.
