Prasanth Jayachandran commented on HIVE-12598:
----------------------------------------------
If using synthetic file id can lead to correctness issues, why would anyone
want to use synthetic file id? Why not just disable it always if filesystem is
not HDFS?
> LLAP: disable fileId when not supported
> ---------------------------------------

> There is a TODO somewhere in code. We might get a synthetic fileId in absence
> of the real one in some cases when another FS masquerades as HDFS, we should
> be able to turn off fileID support explicitly for such cases as they are not
> bulletproof.
