WARN DAGScheduler: Broadcasting large task binary with size 2.2 MiB

Hi there.
There were quite a number of such warnings as the model was getting trained.

22/08/04 07:08:08 WARN DAGScheduler: Broadcasting large task binary with size 1139.5 KiB
22/08/04 07:08:09 WARN DAGScheduler: Broadcasting large task binary with size 2.2 MiB

May I know if we are safe to ignore them?
What does it mean actually?
Thanks in advance.
