HDFS mounting issue using Hadoop-Fuse on Fully Distributed Cluster?
Dear All,
I have installed *Hadoop-fuse* to mount the HDFS filesystem locally . I
could mount the HDFS without any issues.But I am not able to do any file
operations like *delete, copy, move* etc directly. The directory ownership
automatically changed to *nobody:nobody* while mounting.
*[root@namenode ~]# ls -ld /hdfs_mount/
drwxr-xr-x 2 root root 4096 Apr 3 16:22 /hdfs_mount/
[root@namenode ~]# hadoop-fuse-dfs dfs://namenode:8020 /hdfs_mount/** **
INFO fuse_options.c:162 Adding FUSE arg /hdfs_mount/
[root@namenode ~]# ls -ld /hdfs_mount/* *
drwxrwxr-x 10 nobody nobody 4096 Apr 5 13:22 /hdfs_mount/*
I tried the same with *pseudo-distributed node*,but its working fine. I can
do any normal file operations after mounting the HDFS.
Appreciate your help on the same.

Manu,
for clarifying:
root has no access to the mounted HDFS. Just follow the howto:
1. create the group and the users on ALL nodes:
groupadd hdfs-user && adduser USERNAME -G hdfs-user
2. sudo into hdfs:
su - hdfs
3. create a directory in hdfs and change the rights:
hadoop fs -mkdir /someone && hadoop fs -chmod 774 /someone && hadoop fs -chgrp hdfs-user /someone
Now the users you created and added into to group are able to write files.

Yes, as I wrote. You can't use root as user for writing, root (or superuser) has another context in hdfs. Just change into hdfs (su - hdfs) and try again. For all user who should have access to the mounted fs you should create a group and chown them in hdfs (maybe /tmp/group or similar)

Yes, as I wrote. You can't use root as user for writing, root (or superuser) has another context in hdfs. Just change into hdfs (su - hdfs) and try again. For all user who should have access to the mounted fs you should create a group and chown them in hdfs (maybe /tmp/group or similar)

Manu,
did you mount hdfs over fstab:
hadoop-fuse-dfs#dfs://namenode.local:<PORT> /hdfs-mount fuse usetrash,rw 0 0" ?
You could that do with:
"mkdir -p /hdfs-mount && chmod 777 /hdfs-mount && echo "hadoop-fuse-dfs#dfs://NN.URI:<PORT> /hdfs-mount fuse usetrash,rw 0 0" >> /etc/fstab && mount -a ; mount"

Re: HDFS mounting issue using Hadoop-Fuse on Fully Distributed Cluster?

Manu,
did you mount hdfs over fstab:
hadoop-fuse-dfs#dfs://namenode.local:<PORT> /hdfs-mount fuse usetrash,rw 0 0" ?
You could that do with:
"mkdir -p /hdfs-mount && chmod 777 /hdfs-mount && echo "hadoop-fuse-dfs#dfs://NN.URI:<PORT> /hdfs-mount fuse usetrash,rw 0 0" >> /etc/fstab && mount -a ; mount"

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?

As you see, the FS is mounted as nobody and you try as root. Change the permissions in your hdfs:
