Is there any way to invalidate the reuse and ask Hadoop to > resent exactly the same files to cache for every job? I may be able to answer this better if I understand the use case. If you need the same files for every job, why would you need to send them afresh each time ? If something is cached, it can be reused, no ? I am sure I must be missing something in your requirement ... Thanks Hemanth
