> 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.
