fuse-dfs : Transport endpoint is not connected

Hi,

I get the following error when trying to mount the fuse dfs.

[fuse-dfs]$ ./fuse_dfs_wrapper.sh -d dfs://mydevserver.com:9000 /mnt/hadoop/
fuse-dfs ignoring option -d
port=9000,server=mydevserver.com
fuse-dfs didn't recognize /mnt/hadoop/,-2
fuse: bad mount point `/mnt/hadoop/': Transport endpoint is not connected

I followed all the steps at one of the similar threads -
http://www.nabble.com/fuse-dfs-to18849722.html#a18877009 but it didn't
resolve the issue.
I was able to build the fuse-dfs using  ant compile-contrib
-Dlibhdfs=1 -Dfusedfs=1

the /var/log/messages shows the following line:

Dec 28 07:41:10 mydevserver fuse_dfs: mounting dfs://mydevserver.com:9000/

Any pointers to debug this issue ?

Thanks,
Amit

Hey Amit,

The "transport endpoint is not connected" means that you have a FUSE  
endpoint mounted that crashed which you did not unmount before the  
current attempt.

Also, it's fairly pointless to run FUSE-DFS in 0.19.0 without this  
patch:
