Hi, I have submitted a PR for SPARK-11962 ( https://github.com/apache/spark/pull/12708). I have most of it ready except I am not able to pin point the cause for a particular bug.
In the PR I've added two major methods to Row, `attempt` and `getOption`. The former returns a `Try` while the latter returns an `Option`. - `attempt` was added after a comment was made in PR #10247 <https://github.com/apache/spark/pull/10247>, where it was suggested I not return `None` when certain exceptions are thrown. But in my opinion, throwing exceptions from a function which returns an `Option` is not a good use case. - I am not in love with the method name, `attempt`. Would welcome suggestions. I wanted to use `try` but it's a keyword. - So about the failing tests (which shouldn't fail in my opinion), in `RowTest`, all new tests testing for `ClassCastException` fail. I have modified tests as comments in the code blocks (with TODOs) which work, but should behave the same way as the actual test from what I can see. I am not sure what I am doing wrong in the code here. Would appreciate some feedback. Thanks, Arun P. S. I have sent similar emails to the dev mailing list before but I don't see them in the dev archives. I am guessing they were not received as I was not subscribed to the dev list. Hopefully this would work as I have subscribed now.
