Review request for hive, Ashutosh Chauhan and Thejas Nair.
Bugs: hive-5032
https://issues.apache.org/jira/browse/hive-5032
Repository: hive-git
Description
-------
Creating external table using HIVE with location point to the root directory of
DFS will fail because the function
HiveFileFormatUtils#doGetPartitionDescFromPath treat authority of the path the
same as folder and cannot find a match in the "pathToPartitionInfo" table when
doing prefix match. Instead of modify the path string for recursive prefix
match, this patch use Path.getParent() to get the prefix for the path. This
approach solve the failed corner cases of original implementation.
