> We have met such circumstance:
> We are trying to run storm&kafka on yarn by Slider, and Storm&Kafka writes 
> data to local disk on node. If some containers or the application fails, we 
> expect that those containers would restart on the same node as they run 
> before, otherwise data written on local would lost.
> For slider, it will trying to ensure restarted container on same nodes as 
> before. However for yarn, resource may be assigned to other applications when 
> former long-running application is down.
> As a result we'd better to have a mechanism that reserve some resource for 
> certain long-running applications on certain nodes for a period of time. Does 
> it make sense?
