Gopal V commented on HIVE-16296:
--------------------------------
This is a bit strange - I think HDFS has some consistent ordering of files in a
directory when listing it.
I'm getting consistent results without an ORDER BY (i.e the output files are
read in reducer order - reducer 0 files first etc.).
> use LLAP executor count to configure reducer auto-parallelism
