So, you have a successful mount, but for some reason it's not talking
to Hadoop.
Try adding the "-d" flag; this will mount FUSE in debug mode, and any
Hadoop errors (or whatever is causing the Input/output error) will be
printed to the terminal.

We are using Redhat EL5 and hadoop 0.19; We did have some trouble
compiling FUSE-DFS but got through the compilation errors. Any
advice on
what to try next?
