Subject [jira] [Commented] (MAPREDUCE-4043) Secret keys set in Credentials are not seen by tasks
Date Wed, 21 Mar 2012 17:33:41 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4043?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13234553#comment-13234553

Vinod Kumar Vavilapalli commented on MAPREDUCE-4043:
----------------------------------------------------

Can you please check and see if the patch for MAPREDUCE-3727 is the cause? I remember something
like this, credentials being removed from the client as one of the proposals there. Don't
have bandwidth to confirm this myself. Thanks.

>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>          Components: mrv2, security
>    Affects Versions: 0.23.2
>            Reporter: Jason Lowe
>            Priority: Blocker

> The following scenario works in 0.20.205 but no longer works in 0.23:
> 1) During job submission, a secret key is set by calling jobConf.getCredentials().addSecretKey(Text,
byte[])
> 2) A map task retrieves the secret key by calling jobConf.getCredentials().getSecretKey(Text)
> In 205 the secret key is retrieved successfully but in 0.23 the secret key is missing.
