Hi

Because hdfs-site.xml not in CLASSHPATH in the file of fuse_dfs_wrapper.sh.
So you need to edit the fuse_dfs_wrapper.sh and add one line 

export CLASSPATH=<the directory of your hdfs-site.xml>

before this part 

for f in ls $HADOOP_HOME/lib/*.jar $HADOOP_HOME/*.jar ; do
  export CLASSPATH=$CLASSPATH:$f
done

I wish it can resolve your question.
