Subramanyam Pattipaka commented on HIVE-14511:
----------------------------------------------
I mean to add only p1=1/p2=1. For example if you have following structure
data/p1=1/p2=1/p3=1
/p3=2
/p3=3
/p2=2/p3=1
/p3=2
/p1=2/p2=1/p3=1
Now, I want to add only (1,1), (1,2) and (2,1) as partitions. If you remove the
above check then this is possible.
In first iteration you would list
p1=1
p1=2
in next iteration you would list
/p1=1/p2=1
/p1=1/p2=3
/p1=2/p2=1
As depth is 0 we stop here and these are the paths for partitions if user want
to create on p1 and p2 as partition columns. If you want you can check for
existence of use of config mapred.input.dir.recursive and
hive.mapred.supports.subdirectories.

> Some users will have a folder rather than a file under the last partition
> folder. However, msck is going to search for the leaf folder rather than the
> last partition folder. We need to improve that.
