    Description

      While trying to print a warning, two values of the wrong type (Resource instead of int) are passed into a String.format method call, leading to a runtime exception, in the file:

      trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/src/main/java/org/apache/hadoop/yarn/server/resourcemanager/scheduler/fair/QueueManager.java.

      The warning was intended to be printed whenever the resources don't fit into each other, either because the number of virtual cores or the memory is too small. I changed the %d's into %s, this way the warning will contain both the cores and the memory.
