Subject: [jira] [Updated] (HDFS-4056) Always start the NN's SecretManager

Daryn Sharp updated HDFS-4056:
------------------------------

    Attachment: HDFS-4056.patch

Always starting the secret manager caused many edit log related tests to fail because of the unexpected txns caused by a double-roll of the secret key at startup.  I added lazy secret key generation when the first token is created to avoid having to update all those tests.

> To support the ability to use tokens regardless of whether kerberos is enabled, the NN's secret manager should always be started.
