Subject [jira] [Commented] (MAPREDUCE-4550) Key Protection : Define Encryption and Key Protection interfaces and default implementations
Date Tue, 28 Aug 2012 06:34:07 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4550?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13442988#comment-13442988
] 

Konstantin Shvachko commented on MAPREDUCE-4550:
------------------------------------------------

Does it make sense to combine {{Encryptor}} and {{Decryptor}} into a single interface with
two methods {{encrypt()}} and {{decrypt()}}. These algorithms usually come in pairs.

> A secret key is read from a Key Store and then encrypted during transport between JobClient
and Task. The tasktrackers/nodemanagers decrypt the secrets and provide the secrets to child
tasks which part of the job.
> This jira defines the interfaces to accomplish the above :
> 1) KeyProvider - to read keys from a KeyStore
> 2) Encrypter and Decrypter - to and encrypt and decrypt secrets/data.
> The default/dummy implementations will also be added. This includes a KeyProvider implementation
to read keys from a Java KeyStore.
