> We're cleaning up Hive and Spark's use of FileSystem.exists, because it is often the
case we see code of exists+open, exists+delete, when the exists probe is needless. Against
object stores, expensive needless.
> Hadoop can set an example here by stripping them out. It will also show where there are
opportunities to optimise things better and/or improve reporting.
