Github user felixcheung commented on the issue: https://github.com/apache/spark/pull/16330 Right, I was thinking of adding note into the API doc and we could add a log too - to say when you call `sparkR.session()` it will create a metastore and a warehouse location. I think we still need to set `System.setProperty("derby.system.home"` because that's where derby.log goes to, which is not user data but a log file. What do you think - @gatorsmile @cloud-fan @shivaram ?
