----------------------------------
Summary: SchedulerUtils improve way normalizeRequest sets the
resource capabilities
Key: YARN-382
URL: https://issues.apache.org/jira/browse/YARN-382
Project: Hadoop YARN
Issue Type: Improvement
Components: scheduler
Affects Versions: 2.0.3-alpha
Reporter: Thomas Graves
In YARN-370, we changed it from setting the capability to directly setting
memory and cores:
- ask.setCapability(normalized);
+ ask.getCapability().setMemory(normalized.getMemory());
+ ask.getCapability().setVirtualCores(normalized.getVirtualCores());
We did this because before it is directly setting the values in the original
resource object passed in when the AM gets allocated and without it the AM
doesn't get the resource normalized correctly in the submission context. See
YARN-370 for more details.
I think we should find a better way of doing this long term, one so we don't
have to keep adding things there when new resources are added, two because its
a bit confusing as to what its doing and prone to someone accidentally breaking
it in the future again. Something closer to what Arun suggested in YARN-370
would be better but we need to make sure all the places work and get some more
testing on it before putting it in.
