Subject [jira] [Commented] (MAPREDUCE-4043) Secret keys set in Credentials are not seen by tasks
Date Fri, 23 Mar 2012 16:55:27 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4043?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13236779#comment-13236779
] 

Robert Joseph Evans commented on MAPREDUCE-4043:
------------------------------------------------

The patch looks good to me +1 and it looks simple enough.  But I don't understand the tokens
in yarn enough to really feel comfortable with just checking it in myself so I have added
Vinod on to the watch list.

> 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.
