> The following Pool usage cases need to have Unit test coverage :
> - FIFO Scheduler just uses *root pool* so even if *spark.scheduler.pool* property is
set, related pool is not created and *TaskSetManagers* are added to root pool.
> - FAIR Scheduler uses default pool when *spark.scheduler.pool* property is not set. This
can be happened when Properties object is null or empty(*new Properties()*) or points default
pool(*spark.scheduler.pool*=_default_).
> - FAIR Scheduler creates a new pool with default values when *spark.scheduler.pool* property
points _non-existent_ pool. This can be happened when scheduler allocation file is not set
or it does not contain related pool.
