Blocker Description
HADOOP-8783 made a change which caused the SaslRpcServer not to be initialized if there is no secret manager present. This works fine for most Hadoop daemons because they need a secret manager to do their business, but JournalNodes do not. The result of this is that JournalNodes are broken and will not handle RPCs in a Kerberos-enabled environment, since the SaslRpcServer will not be initialized.
