Subject [jira] [Commented] (HADOOP-10427) KeyProvider implementations should be thread safe
Date Thu, 03 Apr 2014 05:27:21 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10427?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13958529#comment-13958529

Alejandro Abdelnur commented on HADOOP-10427:

Thread safety is needed regardless of KMS server, in case a client is doing multithreaded

Agree that the JavaKeyStoreProvider is not the ideal backend for the KMS server. Currently
is the only thing we have in Hadoop. 

The KMS server simply uses the KeyProvider API, so you could plugin any impl there, potentially
one talking with a KMIP server.

The KMS server does not attempt to provide a reliable store, just a client/server implementation
deferring to another implementation.

Sounds reasonable?
