[jira] [Commented] (SPARK-25344) Break large tests.py files into smaller files

    [ https://issues.apache.org/jira/browse/SPARK-25344?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16605250#comment-16605250 ] 

Imran Rashid commented on SPARK-25344:
--------------------------------------

kinda related, maybe this should get its own jira -- when you run the "pyspark-sql" tests, it also somehow runs {{SparkSubmitTests}}, which really should only be in the "pyspark-core" module.  For me they take 80s, would be nice to eliminate that.

I don't really understand why they get run in that module, but it does seem if I comment out the import in sql/tests.py, then they don't get run that extra time.  We can't really do that, as the import is needed for the {{HiveSparkSubmitTests}}.  But we should figure out why just importing it makes them run, and if we can do avoid that.

> We've got a ton of tests in one humongous tests.py file, rather than breaking it out into smaller files.
> Having one huge file doesn't seem great for code organization, and it also makes the test parallelization in run-tests.py not work as well.  On my laptop, tests.py takes 150s, and the next longest test file takes only 20s.  There are similarly large files in other pyspark modules, eg. sql/tests.py, ml/tests.py, mllib/tests.py, streaming/tests.py.
> It seems that at least for some of these files, its already broken into independent test classes, so it shouldn't be too hard to just move them into their own files.
