Subject Re: Difference between Capacity scheduler and Fair Scheduler
Date Wed, 02 Jan 2019 06:54:21 GMT
Hi Ved,

Here is a blog for fair scheduler preemption,
In terms of performance, I'm not aware of any document to compare both
schedulers. The easiest way to do it yourself is using SLS(
SLS focuses on the resource manager rather than anything else, like Node
managers, which is a good thing since FS and CS share the same NM
implantation. I would be surprise their performances drastically differ
from each other for the most common use cases, but their performances would
be very different in some cases.
