Subject [jira] [Commented] (HADOOP-10607) Create an API to Separate Credentials/Password Storage from Applications
Date Tue, 27 May 2014 16:31:02 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10607?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14009861#comment-14009861
] 

Owen O'Malley commented on HADOOP-10607:
----------------------------------------

Larry, some comments:
* please change CredShell to CredentialShell
* in CredShell.promptForCredential you clobber the array before returning it.
* it would be really nice for CredShell to have more unit tests. I'm not quite sure how to
get there.

> As with the filesystem API, we need to provide a generic mechanism to support multiple
credential storage mechanisms that are potentially from third parties. 
> We need the ability to eliminate the storage of passwords and secrets in clear text within
configuration files or within code.
> Toward that end, I propose an API that is configured using a list of URLs of CredentialProviders.
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. 
> A CredShell CLI will also be included in this patch which provides the ability to manage
the credentials within the stores.
