Jerry Chen commented on HADOOP-10141:
-------------------------------------
Owen, the way this JIRA is going really confused me.
Just as mentioned, "the part of HADOOP-9333 that does similar things doesn't
address the requirements". Why not improve based the existing work to satisfiy
the requirements other than starting a separate one? since HADOOP-9333 has not
closed yet.

> As with the filesystem API, we need to provide a generic mechanism to support
> multiple key storage mechanisms that are potentially from third parties.
> An additional requirement for long term data lakes is to keep multiple
> versions of each key so that keys can be rolled periodically without
> requiring the entire data set to be re-written. Rolling keys provides
> containment in the event of keys being leaked.
> Toward that end, I propose an API that is configured using a list of URLs of
> KeyProviders. The implementation will look for implementations using the
> ServiceLoader interface and thus support third party libraries.
> Two providers will be included in this patch. One using the credentials cache
> in MapReduce jobs and the other using Java KeyStores from either HDFS or
> local file system.
