Thanks a lot Jose,

I’ll look into the issue you’ve recommended then. Will comment on Jira to indicate I’m
working on it and ask further questions there if needed.

I can't speak for the other tasks, but SPARK-23444 I'd expect to be pretty complicated. It's
not obvious what the right strategy is, and there's a bunch of minor stuff that needs to be
cleaned up (e.g. tasks shouldn't print cancellation warnings when cancellation is expected).

If you're interested in working on continuous processing,
could be a good newbie task. It's a pretty localized change to the EpochCoordinator class;
basically, it needs to wait to call query.commit(n + 1) until after query.commit(n). I'm not
sure how well I've managed to document the existing implementation, but I'd be happy to answer
any questions about it.

Good time of day,

I’d like to contribute to Spark development, but find it difficult to get into the process.
I’m somewhat overwhelmed by Spark’s Jira as it’s hard for me to figure out the complexity
of tasks and choose an appropriate one.
I’ve surfed Jira for some time and have selected a few issues I think I could try to solve: - although for this one there’s an uncertainty
that it’s needed at all, according to the comment

Also I think it would be interesting to work on Continuous Processing if there were some newbie
tasks, but I wasn’t able to find them.
If you could give me some directions on any of these issues I’ve linked, or just point to
some tasks that are suitable for a beginner, that’d help me a lot, I would appreciate any

Best regards,
