Subject [jira] [Commented] (HDFS-4056) Always start the NN's SecretManager
Date Wed, 17 Oct 2012 19:28:03 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4056?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13478279#comment-13478279
] 

Daryn Sharp commented on HDFS-4056:
-----------------------------------

bq. the job client will always fetch a NN delegation token for the job
This is the misunderstanding.  The patch does not force clients or job submission to obtain
a token.  The client simply has the option of requesting and using a token, but the client
can still continue to run with no token as it does today.

I'd suggest we debate the pros and cons of adding another conf setting for whether clients
will always use tokens with simple auth on the other jiras linked to the parent of this jira.
 Fair enough?

secret manager should always be started.
