Add a new resource type in resource-types.xml, eg: resource1.
In Fair scheduler when queue's MaxResources is configured like:

<maxResources>4096 mb, 4 vcores</maxResources>

When submit a application which need resource like:

 1536 mb, 1 vcores, 10 resource1

The application will be pending. Because there is no resource1 in this queue.
