-----------------------------------------
[~joshrosen] - Per [this comment |
https://issues.apache.org/jira/browse/SPARK-3431?focusedCommentId=14168038&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14168038],
are you saying we have a way to parallelize tests and the only problem is the
interleaved output? How quickly do tests run in that mode?
I thought another problem we had with parallelizing tests was that certain
tests fought over the same ports or something. Is that not the case?

> Running all the tests in {{dev/run-tests}} takes up to 2 hours. A common
> strategy to cut test time down is to parallelize the execution of the tests.
> Doing that may in turn require some prerequisite changes to be made to how
> certain tests run.
