WARN BlockManager: Block rdd_6_0 already exists on this machine; not re-adding it

Hi there.
I am working with Vertex AI Jupyterlab Notebook.
There were a few such warnings

WARN BlockManager: Block rdd_6_0 already exists on this machine; not re-adding it
WARN BlockManager: Block rdd_817_0 already exists on this machine; not re-adding it

on this as the model was getting trained.
May I know if we are safe to ignore this?
What do they mean actually?
Thanks in advance.

No, you should not worry since this is just a warning that tells you that those two blocks will not be re added to your notebook.

Thanks for confirming.
