fuse-dfs:fuse-dfs didn't recognize /dfs,-2
Hi,
I get the following error when trying to mount the fuse dfs,
the first problem is:
[root@puppet ~]# fuse_dfs_wrapper.sh dfs://100.207.100.25:9000/ /dfs
port=9000,server=100.207.100.25
fuse-dfs didn't recognize /dfs,-2
the second problem is:
then i cd /dfs,
[root@puppet dfs]# ls -l
total 0
?--------- ? ? ? ? ? n:9000/1
?--------- ? ? ? ? ? n:9000/tmp
?--------- ? ? ? ? ? n:9000/user
when use -d option,like
[root@puppet ~]# fuse_dfs_wrapper.sh dfs://100.207.100.25:9000/ /dfs -d
port=9000,server=10.207.0.25
fuse-dfs didn't recognize /dfs,-2
fuse-dfs ignoring option -d

Are you by chance running 0.19.0?
That ls output looks like 0.19.0's output.

For some reason, this always happens. It's not an error, it's some
sort of warning.

Try this; it's confused about the prefix you've given it (it's a bit
picky about this)
fuse_dfs -oserver=100.207.100.25 -oport=9000 /dfs -oallow_other -
ordbuffer=131072
By the way - as you explore HDFS, you'll want to switch from IP
address to hostnames at some point.
