dhruba borthakur commented on HADOOP-5445:

Can you pl explain what files does this utility delete?

Also, HDFS support access times and modification times starting with the 0.19 release.

> 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).
