Owen O'Malley commented on HADOOP-10757:
----------------------------------------
There is already a utility function to parse the keyversions. As we've
discussed in each of the other jiras where you've brought this up, changing the
keyversion to a UID is an anti-goal.
> KeyProvider KeyVersion should provide the key name

> Key: HADOOP-10757
> URL: https://issues.apache.org/jira/browse/HADOOP-10757
> Project: Hadoop Common
> Issue Type: Improvement
> Components: security
> Affects Versions: 3.0.0
> Reporter: Alejandro Abdelnur
> Assignee: Arun Suresh
>
> Currently the {{KeyVersion}} does not provide a way to get the key name to do
> a reverse lookup to get the metadata of the key.
> For the {{JavaKeyStoreProvider}} and the {{UserProvider}} this is not an
> issue because the key name is encoded in the key version name.
> This encoding of the key name in the key version name cannot be expected in
> all KeyProvider implementations. It is common for key management systems to
> use UUID to refer to specific key materials (KeyVersions in Hadoop parlance).
