>
> In a secured cluster, the JournalNode validates that the caller is one of a 
> valid set of principals.  One of the principals considered is that of the 
> SecondaryNameNode.  This involves checking 
> {{dfs.namenode.secondary.http-address}} and trying to interpret it as a 
> network address.  If a user has specified a value for this property that 
> cannot be interpeted as a network address, such as "null", then this causes 
> the JournalNode operation to fail, and ultimately the NameNode cannot start.  
> The JournalNode should not have a hard dependency on 
> {{dfs.namenode.secondary.http-address}} like this.  It is not typical to run 
> a SecondaryNameNode in combination with JournalNodes.  There is even a check 
> in SecondaryNameNode that aborts if HA is enabled.
