Re: Yarn hangs @Scheduled
I fixed the issue by setting

yarn.scheduler.minimum-allocation-mb=1024

I'm thinking this happens a lot in VMs where you run w low memory.

If memory too low, I think other failures will occur at runtime when you start daemons or tasks...If too high, then the tasks will hang...
