---------------------------

             Summary: HDFS Plugin does not allow removal of a non-empty directory if the directory is allowed to be removed by HDFS, but the file inside the directory is allowed to be removed by Ranger
                 Key: RANGER-1181
                 URL: https://issues.apache.org/jira/browse/RANGER-1181
             Project: Ranger
          Issue Type: Bug
          Components: plugins
    Affects Versions: 0.6.1
            Reporter: Yan


Reproduction Steps:
1. Ranger is installed and HDFS plug-in is enabled.
2. As qaadmin user, create a folder on HDFS with permission 500:
hadoop fs -mkdir /tmp/rangertest1
hadoop fs -chmod 500 /tmp/rangertest1

while the /tmp itself has the 777 as the HDFS bits:
hadoop fs -ls /
drwxrwxrwx   - user1 group1          0 2016-10-03 14:54 /tmp

3. Create a Ranger policy p1_1 by granting qaadmin with RWX permission to the folder of /tmp/rangertest1, recursive set to true 
4. Wait for around >30 seconds after Policy synced up.
5. Put a file to /tmp/rangertest1 folder:
echo "This is a file2" > /tmp/temp
hadoop fs -put /tmp/temp /tmp/rangertest1
hadoop fs -ls /tmp/rangertest1
Found 1 items
-rw-r--r--   3 qaadmin hdfs         16 2016-09-21 19:13 /tmp/rangertest1/temp
6. Try to delete the non-empty folder with "-skipTrash" option, but it failed (delete the empty folder could success): 
[qaadmin@biwangxj1 RangerPlugIn]$ hadoop fs -rm -r -skipTrash /tmp/rangertest1
rm: Permission denied: user=qaadmin, access=ALL, inode="/tmp/rangertest1":qaadmin:hdfs:dr-x------
