The original code version seems to be warning about full task, including
rdd, shuffle dep, closures, partition and so on.
I think that the previous warning code was retained because the #1498 did
not completely modify it,
In most cases, the size of serialized TaskDescription is smaller than
tasks`s Broadcast.
