the problem of container assigning.There are too many records like this in yarn-resourcemanager.log,

> The reason why of so many records is that it always print this info first in container
assigning whether the assigned result is successful or failed.
> Can see the complete yarn log in updated log, and you can see how many records there
are.
> And in addition, too many these info logging will slow down process of container assigning.Maybe
we should change this logLevel to other level, like {{trace}}.
