Subject [jira] [Commented] (HDFS-4056) Always start the NN's SecretManager
Date Tue, 16 Oct 2012 17:57:03 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4056?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13477213#comment-13477213
] 

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

After this change SIMPLE + SIMPLE will work just as it always has.  The only difference is
that tokens may be requested and used with SIMPLE auth.

Based on discussions in HADOOP-8758 and HADOOP-8779, the agreement was to always enable tokens.
 Doing so will actually help eliminate the instability in the token system because the tests
will detect if a change has broken tokens.  Complexity will be reduced by removing code paths
and we'll increase the code coverage.

secret manager should always be started.
