-------------------------------------
Summary: Key Distribution and Management for supporting crypto
codec in Map Reduce
Key: MAPREDUCE-5025
URL: https://issues.apache.org/jira/browse/MAPREDUCE-5025
Project: Hadoop Map/Reduce
Issue Type: Sub-task
Components: security
Affects Versions: trunk
Reporter: Jerry Chen
Assignee: Jerry Chen
This task defines the work to enable Map Reduce to utilize the Crypto Codec
framework to support encryption and decryption of data during MapReduce Job.
According to the some real use case and discussions from the community, for
encryption and decryption files in Map Reduce, we have the following
requirements:
1. Different stages (input, output, intermediate output) should have the
flexibility to choose whether encrypt or not, as well as which crypto codec to
use.
2. Different stages may have different scheme of providing the keys.
3. Different Files (for example, different input files) may have or use
different keys.
4. Support a flexible way of retrieving keys for encryption or decryption.
So this task defines and provides the framework for supporting these
requirements as well as the implementations for common use and key retrieving
scenarios.
