Swapnil Daingade commented on YARN-2139:
----------------------------------------
Had a look at the latest design doc and was wondering if it would be possible
to make the isolation part separate and optional from the avoiding
over-allocation part. Enforcing isolation using Cgroups may not always work,
especially in cases where HDFS is not the default dfs.
