Eric Yang commented on HADOOP-14063:
------------------------------------
Agree with Yan that FileNotFound exception should not be captured to preserve
existing semantic. For AccessControlException, it would be right to handle the
exception and return false. This would be closer to the original
implementation.

> The {{hadoop.security.credential.provider.path}} property can be a list of
> keystore files like this:
> _jceks://hdfs/file1.jceks,jceks://hdfs/file2.jceks,jceks://hdfs/file3.jceks
> ..._
> Each file can have different permissions set to limit the users that have
> access to the keys. Some users may not have access to all the keystore files.
> Each keystore file in the list should be tried until one is found with the
> key needed.
> Currently it will throw an exception if one of the keystore files cannot be
> loaded instead of continuing to try the next one in the list.
