Ashutosh Chauhan commented on HIVE-13901:
-----------------------------------------
If FileSystem implements listFiles(Path p, boolean recursive) or
listStatus(Path[]) then we won't need this multithreaded approach. Seems like
atleast HDFS has efficient implementation of listFiles(Path, boolean).
> Hivemetastore add partitions can be slow depending on filesystems
