How can I write my own Hadoop scheduler?

I've been studying hadoop's scheduler mechanism recently. Using 0.20.2(fair&capaci开发者_开发百科ty included) Have read some papers, LATE\Deadline Scheduler...

Has anyone tried? or is there a guide?

thx anyway


If you plan to do your own scheduler maybe you could consider a document from author Datta Dhok - Learning based admission control and task assignment in mapreduce. They did some job on admission control and a learning based hadoop scheduler. Source code is available. Did you find any other documents on these subject?
