Thejas M Nair commented on HIVE-4239:
-------------------------------------
I haven't looked at this in depth, but a potential way to make things not worse
in above use case, would be to have a synchronize keyword for Driver.compile().
That way the compile lock is not global, but local to a hiveserver2 session.
> Remove lock on compilation stage
