------------------------------------
Summary: Fair Scheduler :ability to configure minResources and maxResources in
terms of percentage
Key: YARN-2162
URL: https://issues.apache.org/jira/browse/YARN-2162
Project: Hadoop YARN
Issue Type: Improvement
Components: scheduler
Reporter: Ashwin Shankar
minResources and maxResources in fair scheduler configs are expressed in terms of absolute
numbers X mb, Y vcores.
As a result, when we expand or shrink our hadoop cluster, we need to recalculate and change
minResources/maxResources accordingly, which is pretty inconvenient.
We can circumvent this problem if we can (optionally) configure these properties in terms
of percentage of cluster capacity.
