> HDFS-3247 improved bootstrapStandby to check if the other NN is in active 
> state before trying to bootstrap. But, it forgot to set up the kerberos 
> principals in the config before doing so. So, bootstrapStandby now fails with 
> "Failed to specify server's Kerberos principal name" in a secure cluster.
