> This has been a known issue, but I think it's about time we address it. Whena  user sets
up a mapreduce, they set their password in the configuration (Base64 encoded). This configuration
is world readable, meaning passwords are out there in cleartext. We need a mechanism in place
to try to keep this data private.
> In hadoop 0.20.203, the private distributed cache was implemented. Any file placed in
the distributed cache which is not world readable/not in folders world executable automatically
get placed in the private distributed cache. The protection mechanism is simply being in the
tasktracker's local directory under a folder for the user with restricted permissions. This
should be adequate for protecting a users Accumulo password. So this should be as simple as
checking the set/getPassword functions to utilize this space rather than the configuration.
