Zhankun Tang created YARN-9205:
----------------------------------
Summary: When using custom resource type, application will fail to
run due to the CapacityScheduler throws
InvalidResourceRequestException(GREATER_THEN_MAX_ALLOCATION)
Key: YARN-9205
URL: https://issues.apache.org/jira/browse/YARN-9205
Project: Hadoop YARN
Issue Type: Bug
Reporter: Zhankun Tang
In a non-secure cluster. Reproduce it as follows:
# Set capacity scheduler in yarn-site.xml
# Use default capacity-scheduler.xml
# Set custom resource type "cmp.com/hdw" in resource-types.xml
# Set a value say 10 in node-resources.xml
# Start cluster
# Submit a distribute shell application which requests some "cmp.com/hdw"
The AM will get an exception from CapacityScheduler and then failed. This bug
doesn't exist in FairScheduler.

...{code}
Did a roughly debugging, below method should return the wrong maximum capacity.
DefaultAMSProcessor.java, Line 234.
{code:java}
Resource maximumCapacity =
getScheduler().getMaximumResourceCapability(app.getQueue());{code}
The above code seems should return "<memory:8192, vCores:4, cmp.com/hdw:10>"
but returns "<memory:8192, vCores:4>".
