> Also, because of that method, the return value of
getConf(CHECKPOINT_LOCATION) would be String and not Option[String], which is
probably why intellij is complaining.
Well, it actually depends on which one of the overloads you are invoking,
which is why I found this design confusing. I guess with the explicit type
you can hint to the scala compiler which one you want to call? and the intelij
compiler is less advanced?
What is the correct way to ask if an optional configuration is set or not?
