------------------------------------------
This is a good tool, I agree. There are lots of unix-y tools that we can port
to HDFS. One way to make them all run transparently on Hadoop file system is to
use the fuse mount http://wiki.apache.org/hadoop/MountableHDFS. This allows a
large chunk of unix-y tools to run on HDFS.
In our installation, we mount hdfs on one machine through fuse. Then we run
some periodic (via cron) unix utilities that does cleaning/minitoring/reporting
of HDFS in standard UNIX-filesystem-type ways. Will such a approach satisfy
your needs?

> Java implementation of tmpreaper utility for HDFS. Helps when you expect
> processes to die before they can clean up. I have perl unit tests that can
> be ported over to java or groovy if the hadoop team is interested in this
> utility. One issue is that the unit tests set the modification time of test
> files, which is unsupported in HDFS (as far as I can tell).
