(Sorry for the delay)
> Invalid string format in Fair Scheduler log warn message

> Key: YARN-1351
> URL: https://issues.apache.org/jira/browse/YARN-1351
> Project: Hadoop YARN
> Issue Type: Bug
> Components: resourcemanager
> Reporter: Konstantin Weitz

>
> 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.
