Today we merged a pull request which changes the organization of the
scripts use to run Spark. The change is fairly minor but it will
affect anyone who packages spark or uses spark's binary scripts.
Spark's scripts are now divided into a /bin and /sbin directories.
This will be the layout in Spark 0.9.
/sbin contains administrative scripts for launching the standalone
This allows administrators to set permissions differently for user and
admin scripts. It is also consistent with the way many other projects
package binaries. This change was contributed by @xiajunluan,
@shane-huang, and @ScrapCodes.
