> Key: YARN-4819
> URL: https://issues.apache.org/jira/browse/YARN-4819
> Project: Hadoop YARN
> Issue Type: Bug
> Components: scheduler-load-simulator
> Reporter: Rohith Sharma K S
>
> 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.
