Description

https://github.com/apache/storm/blob/master/storm-server/src/main/java/org/apache/storm/scheduler/resource/strategies/scheduling/GenericResourceAwareStrategy.java#L123

2020-02-24 14:53:59.652 o.a.s.s.r.s.s.GenericResourceAwareStrategy pool-21-thread-1 [WARN] Scheduling [[1, 1]] left over task (most likely sys tasks)

This message seems to be confusing on debugging.

https://github.com/apache/storm/blob/master/storm-server/src/main/java/org/apache/storm/scheduler/resource/strategies/scheduling/DefaultResourceAwareStrategy.java#L82

Default Strategy actually uses debug level instead of warn.
