Is this the stderr output from a woker? Are any files being written?
Can you run in debug and see how far it's getting?
This to me doesn't give me a direction to look without the actual logs
from $SPARK_HOME or the stderr from the worker UI.
Just imho maybe someone know what this means but it seems like it
could be caused by a lot of things.

In the spark console, it says 0/32 tasks and just sits there. No
movement.
Thanks in advance,
