Steve Loughran commented on YARN-4276:
--------------------------------------
There's been some discussion about requesting IO resources in containers:
bandwidth/IOPs. It'd be more complex, but
# gives admins more control over limits
# allow better performance guarantees for allocated nodes
# permit cgroup throttling of IO
# force the container requests to be explicit in their IO needs, for consistent
performance on idle/busy nodes
IO resource allocations wouldn't work with HDFS; its a separate process.
Anyway, there is a YARN JIRA somewhere, awaiting someone (you?) to work on it
> Per-application-type local dirs for NodeManager
> -----------------------------------------------
