Namit Jain commented on HIVE-3072:
----------------------------------
Also, the DML support would require complete support for running tests on
hadoop 23 (or some version of hadoop
which has support for nested directories). I know, there are a couple of jiras
for making it work, like HIVE-3341,
but they are not done yet.
Also, these are independent and we should reduce dependencies on HIVE-3341 as
far as possible.
