> SLS requested containers are always assigned in off-switch mode. And scheduler will never allocate any containers for Node-Local and Rack-local mode. 
> The reason for the above behavior is parsing of jobinput file for container host and rack. The input given in job file for rack and node is like below.
> {code}"container.host" : "/default-rack/node1",{code}. But after parsing , the resource request sent for rack is "default-rack" which misses slash('/'). While container allocation during node heartbeat , node rack  name is resolved for rack which is */default-rack* with which look up for resource request for this rack returns null. So, All the requests are assigned to off-switch.
