Hi Alo, I tried to fresh build of fuse-dfs and this time I mount in /mnt but facing same issues. I edited the "fuse_dfs_wrapper.sh" script and added $JAVA_HOME/jre/lib/*.jar in the CLASSPATH , echoed the env variable and then tried again but no luck. Getting same error. Below is the trace:

This is the output with fresh build of fuse-dfs. CLASSPATH variable contains Hadoop*.jar, and $JAVA_HOME/jre/lib/*jar files. JAVA_HOME is set differently also What I am doing wrong. Any Idea ??
