Hi TD,
That little experiment helped a bit. This time we did not see any
exceptions for about 16 hours but eventually it did throw the same
exceptions as before. The cleaning of the shuffle files also stopped much
before these exceptions happened - about 7-1/2 hours after startup.

Hi TD,
That may very well have been the case. There may be some delay on our
output side. I have made a change just for testing that sends the output
nowhere. I will see if that helps get rid of these errors. Then we can try
to find out how we can optimize so that we do not lag.
Questions: How ca
What was the state of your streaming application? Was it falling behind
with a large increasing scheduling delay?

Thanks for the response, Conor. I tried with those settings and for a while
it seemed like it was cleaning up shuffle files after itself. However,
after exactly 5 hours later it started throwing exceptions and eventually
stopped working again. A sample stack trace is below. What is curious about

Hi,
We set the spark.cleaner.ttl to some reasonable time and also
set spark.streaming.unpersist=true.
Those together cleaned up the shuffle files for us.

We already do have a cron job in place to clean just the shuffle files.
However, what I would really like to know is whether there is a "proper"
way of telling spark to clean up these files once its done with them?
Thanks

Hi all,
I had posed this query as part of a different thread but did not get a
response there. So creating a new thread hoping to catch someone's
attention.
We are experiencing this issue of shuffle files being left behind and not
being cleaned up by Spark. Since this is a Spark streaming applica
