Yes, this is one advantage of multi protocol file access to the Isilon HDFS root, you can use native data management commands. Everything Big Data at EMC  Mount an NFS export to your Isilon from one of you client nodes and you can manage data natively without needing to use hdfs commands. As long as the permissions allow this, clearly on the cluster directly root can do what it needs to do.  Also great for loading data directly to you HDFS root.   russ
We understand that trash clean up does not happen in Isilon hdfs as in traditional hadoop. Instead of writing hdfs dfs -rm commands... would it be ok to remove directoy from ISILON filesystem using normal rm command  is4-1$ ls -ltra /ifs/is4/HDFS/elz_uat/user/pcenteru/.Trash/Current/hive/gphd  total 57  drwxrwx---     3 pcenteru  hadoop    22 Feb 10 06:19 ..  drwxrwx---     3 pcenteru  hadoop    27 Feb 10 06:19 .  drwx------    13 pcenteru  hadoop  1039 Feb 11 11:40 warehouse   Files under warehouse directory. Is it a good to practice to run rm /ifs/is4/HDFS/elz_uat/user/pcenteru/.Trash/Current/hive/gphd/warehouse/*.*  as root. Please advice. Thanks Ashok
