We also see this issue at CDH5.7.2 which is based on hadoop 2.6 release +
patches from hadoop 2.7 release, I studied most of the code paths I found two
potential corner cases which may cause this issue:
1. maximum allocation can be changed based on node added and removed and total
resource changed on the node. if maximum allocation is changed to 0
transiently, this issue may happen. since the following code at
CapacityScheduler.allocate will change ResourceRequest in ask to 0 if
getMaximumResourceCapability is 0.
{code}
SchedulerUtils.normalizeRequests(
ask, getResourceCalculator(), getClusterResource(),
getMinimumResourceCapability(), getMaximumResourceCapability());
{code}
2. capability from resource request in application returned without cloning in
LeafQueue.assignContainer and AppSchedulingInfo.cloneResourceRequest and
AppSchedulingInfo.getResource, Potentially the capability in resource request
returned can be changed outside.
I implemented a patch which fixed the first potential corner case based on
branch-2.7. We already deployed this patch for more than one month, so far we
didn't see this issue happen with the attached patch.
The stack trace for the exception is

bq. RM does not dies unless yarn.dispatcher.exit-on-error is set to true
Ignore this. RM sets this configuration to true neverthless of configured value.
In YARN-382 ResourceRequest is validated via normalization process.
Normalization of resources make sure always minimum-allocation-mb for
containers even if users send 0 as container memory.
I verified in real cluster by sending 0 as container memory and am memory.
Schedulers normalize the requests and allocates configured
yarn.scheduler.minimum-allocation-mb.
[~hoelog] Could you give scenario when it happened?
