Daniel Templeton updated YARN-5613:
-----------------------------------
Attachment: YARN-5613.001.patch
The issue shows up when running
{{TestAMRMClient.testAMRMClientWithBlacklist()}} using fair scheduler as the
default. The error is:
{noformat}
expected:<0> but was:<1>
Stacktrace

This patch appears to resolve the issue, but I'm still testing.

> the blacklist. If the scheduler processes the resource request before the
> allocating thread updates the blacklist, the scheduler can assign containers
> that are on nodes in the blacklist.
