---------------------------------------------------------------

I have some minor issues. I was working on compiling on Friday afternoon, but Doug beat me to it with identical comments ;-)


 * I see that the ant script calls the make file, with the correct env vars overridden. In that case, do we need the bootstrap, automake, configure etc? Why not a simpler build system like that used by libhdfs etc? The makefile contains references to the system that configure was run on.
 * build-contrib.xml in patch3.txt has the wrong path.
 * I think it would be better if the built fuse_dfs module was placed in $HADOOP_HOME/contrib/fuse-dfs, in a similar manner to libhdfs, etc
 * If we're keeping configure et al:
 ** README.BUILD refers to bootstrap.sh, while the script is plain_bootstrap.sh
 ** the configure script doesnt identify the JARCH for non-64bit platforms - see config.log for my platform
{code}
configure:1377: checking target system type
configure:1391: result: i686-pc-linux-gnu
{code}
but JARCH is unset, should be i386. I presume this works ok from the ant script?
 * fuse_dfs_wrapper.sh has some issues - perhaps you could base this more closely on the fuse_dfs.sh I attached previously to this JIRA?
  ** various variables have to be written in, eg JAVA_HOME, OS_ARCH has already been identified in configure/ant?, why cant they be set in the script?
  ** fuse_dfs should be called with "$@" instead of $1 $2
  ** the classpath is hard-coded - why can't you identify all the classpath automatically from the HADOOP_HOME path?
 

Will test new build in due course.

Maurizio - see http://en.wikipedia.org/wiki/Patch_(Unix) and apply the patch to a recent release of Hadoop. It requires FUSE.
