Hello,
I am trying to debug a PySpark program and quite frankly, I am stumped.
I see the following error in the logs. I verified the input parameters - all
appear to be in order. Driver and executors appear to be proper - about 3MB of
7GB being used on each node.
I do see that the DAG plan that is being created is huge. Could it be due to
that?
Thanks!
