Any way for users to help "stuck" JIRAs with pull requests for Spark 2.3 / future releases?

[Ewan Leith <ew...@realitymine.com>]

Hi all,

I was wondering with the approach of Spark 2.3 if there's any way us "regular" users can help advance any of JIRAs that could have made it into Spark 2.3 but are likely to miss now as the pull requests are awaiting detailed review.

For example:

https://issues.apache.org/jira/browse/SPARK-4502 - Spark SQL reads unneccesary nested fields from Parquet

Has a pull request from January 2017 with significant performance benefits for parquet reads.

https://issues.apache.org/jira/browse/SPARK-21657 - Spark has exponential time complexity to explode(array of structs)

Probably affects fewer users, but will be a real help for those users.

Both of these example tickets probably need more testing, but without them getting merged into the master branch and included in a release with a default config setting disabling them, the testing will be pretty limited.

Is there anything us users can do to help out with these kind of tickets, or do they need to wait for some additional core developer time to free up (I know that's in huge demand everywhere in the project!).

Thanks,
Ewan
