--------------------------------------
Summary: Create an API to separate encryption key storage from
applications
Key: HADOOP-10141
URL: https://issues.apache.org/jira/browse/HADOOP-10141
Project: Hadoop Common
Issue Type: Bug
Components: security
Reporter: Owen O'Malley
Assignee: Owen O'Malley
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.
