----------------------------------------------------
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.
