distributed cache
Lin Ma 2012-12-22, 12:03
Hi guys,

I want to confirm when on each task node either mapper or reducer access
distributed cache file, it resides on disk, not resides in memory. Just
want to make sure distributed cache file does not fully loaded into memory
which compete memory consumption with mapper/reducer tasks. Is that correct?

thanks in advance,
Lin
