-ZooKeeper FUSE (File System in Userspace)
-=========================================
-
-Pre-requisites
---------------
-1. Linux system with 2.6.X kernel.
-2. Fuse (Filesystem in Userspace) must be installed on the build node. 
-3. Development build libraries:
-  a. fuse
-  b. log4cxx
-  c. pthread
-  d. boost
-
-Build instructions
-------------------
-1. cd into this directory
-2. autoreconf -if
-3. ./configure
-4. make
-5. zkfuse binary is under the src directory
-
-Testing Zkfuse
---------------
-1. Depending on permission on /dev/fuse, you may need to sudo -u root.
-   * If /dev/fuse has permissions 0600, then you have to run Zkfuse as root.
-   * If /dev/fuse has permissions 0666, then you can run Zkfuse as any user.
-2. Create or find a mount point that you have "rwx" permission. 
-   * e.g. mkdir -p /tmp/zkfuse
-3. Run Zkfuse as follows:
-   zkfuse -z <hostspec> -m /tmp/zkfuse -d
-   -z specifies ZooKeeper address(es) <host>:<port>
-   -m specifies the mount point
-   -d specifies the debug mode.
-   For additional command line options, try "zkfuse -h".
-
-FAQ
----
-Q. How to fix "warning: macro `AM_PATH_CPPUNIT' not found in library"?
-A. * install cppunit (src or pkg) on build machine
-
-Q. Why can't Zkfuse cannot write to current directory?
-A. * If Zkfuse is running as root on a NFS mounted file system, it will not
-     have root permissions because root user is mapped to another user by
-     NFS admin.
-   * If you run Zkfuse as root, it is a good idea to run Zkfuse from a
-     directory that you have write access to. This will allow core files
-     to be saved.
-
-Q. Why Zkfuse cannot mount?
-A. * Check that the mount point exists and you have "rwx" permissions.
-   * Check that previous mounts have been umounted. If Zkfuse does not 
-     exit cleanly, its mount point may have to be umounted manually. 
-     If you cannot umount manually, make sure that there no files is open 
-     within the mount point.
-
-Q. Why does Zkfuse complain about logging at startup?
-A. * Zkfuse uses log4cxx for logging. It is looking for log4cxx.properties
-     file to obtain its logging configuration.
-   * There is an example log4cxx.properties file in the Zkfuse source 
-     directory.
