Thanks a lot Alex. Actually I didn't tried the NFS option, as I am trying to sort out this hadoop-fuse mounting issue. I can't change the ownership of mount directory after hadoop-fuse mount.
[root@namenode ~]# ls -ld /hdfs_mount/ drwxrwxr-x 11 nobody nobody 4096 Apr 9 12:34 /hdfs_mount/ [root@namenode ~]# chown hdfs /hdfs_mount/ chown: changing ownership of `/hdfs_mount/': Input/output error Any ideas?
