------------------------------------
[~rkanter]
What if the user stored principal's in different files? Especially SPNEGO
principal as it can be shared among various services like node manager,
datanode etc. We store the oozie service principal and the spnego principal in
different files. Can the user specify a CLS of keytabs?

> When you use Oozie HA with Kerberos, you have to set
> {{oozie.authentication.kerberos.principal}} to {{HTTP/<load-balancer-host>}}
> instead of {{HTTP/<oozie-server-host>}}. This allows clients to connect to
> any of the Oozie servers through the load balancer. However, it also blocks
> clients from directly talking to any of the Oozie servers. In and of itself,
> that's okay, but it turns out that in most cases, it also blocks the Oozie
> servers from talking to each other, namely for log streaming, the
> sharelibupdate command, and collating instrumentation/metrics (OOZIE-1676).
> Ultimately, what we need to do is allow Oozie to use both
> {{HTTP/<load-balancer-host>}} instead of {{HTTP/<oozie-server-host>}} at the
> same time so that clients (including Oozie servers, users, Web UI, etc) can
> talk to Oozie both through the load balancer and directly. If my
> understanding of HADOOP-10158 is correct, HADOOP-10158 adds this ability.
> For this JIRA, we should update Oozie to take advantage of HADOOP-10158.
