Miklos Szegedi commented on YARN-5725:
--------------------------------------
I will use YARN-5725 to track YARN-5726 as well. They belong to different
features. That is why I separated YARN-5725 and YARN-5726.
The source of the null pointer is a mock object that only returns an empty
container map. This is just a test issue AFAIK.
{code}
context = Mockito.mock(Context.class);
Mockito.doReturn(new ConcurrentSkipListMap<ContainerId, Container>())
.when(context).getContainers();
{code}
> Test uncaught exception in
> TestContainersMonitorResourceChange.testContainersResourceChange when setting
> IP and host
