Re: How to timeout a task?

[William Ferrell <wf...@gmail.com>]

Ted,

Thanks very much for your reply. It took me almost a week but I have
finally had a chance to implement what you noted and it appears to be
working locally. However, when I launch this onto a cluster on EC2 -- this
doesn't work reliably.

To expand, I think the issue is that some of the code we have takes the
python GIL and hence no internal timeout will work. That is why I was
hoping to learn of a task level timeout -- something at the Spark level --
the management level -- such that it can decide a task has taken to long
and just kill it and move on.

Does this make sense?  Are you familiar with any such options?

Best,

- Bill
