Boris Shkolnik commented on HADOOP-6325:
----------------------------------------

Note that the credentials will be disjoint for different HDFS clusters (or
other filesystems). So it will look like:
"hdfs://nn1/" -> binary blob1
"hdfs://nn2/" -> binary blob2
"mapred.job.token" -> binary blob3
This key storage should be included in the call to submitJob.

If the keys are given on a command line - how can we pass it to the job. All
the command lines arguments are passed thru config, and we want to avoid id.
> need security keys storage solution
