Charles Reiss commented on MESOS-204:
-------------------------------------
It would probably make more sense to use the cgroups blkio controller
(http://www.kernel.org/doc/Documentation/cgroups/blkio-controller.txt),
assuming you'll have a recent enough kernel. Network prioritization can
probably be done similarly. This probably just hasn't been a big priority for
people because there are nastier issues with isolation, e.g. MESOS-47.
For I/O isolation, one issue is that HDFS (or other DFS) will probably create
priority inversion issues in most real installations. It's not clear how to
deal with this problem.
> enable Frameworks level disk IO bandwidth support

> Key: MESOS-204
> URL: https://issues.apache.org/jira/browse/MESOS-204
> Project: Mesos
> Issue Type: Brainstorming
> Reporter: Qinghe Jin
>
> I am considering to add Frameworks level disk IO bandwidth support to
> mesos，which behaves like ionice on the single node，but this time it‘s in
> multi-nodes。I believe this kind of disk QoS support will be more user
> friendly。My initial idea is to allow user to use an ioprio_set like api to
> set the io priority when they commit their job. At the same time, here may
> need some tools to display the disk IO usage per node/container on the webui.
> I have read the mesos paper carefully and I found that in the comment，it
> mentioned that in the future it will support disk and network bandwidth
> control。But，in my opinion，disk IO bandwidth is more feasible for it has more
> locality，and network bandwidth control may be more difficult for the
> complexity of the network environment。But I don't know why is there nobody
> going to add this feature。Is it useless？Or not feasible？Or just not
> interested？
> For this feature may need a lot of work，I‘d like to listen to your opinions
> before I start to work on it。Anybody who have any questions ,suggestions or
> ideas, please tell me and I appreciate it very much，Thanks！
