Robert Kanter commented on OOZIE-1688:
--------------------------------------

I think oozie.authentication.type and SERVER_SERVER_AUTH_TYPE are two different 
auth type and may have different implementation.
In our case oozie.authentication.type is type of AuthenticationHandler where as 
SERVER_SERVER_AUTH_TYPE is a type of Authenticator.

You're right; it makes sense that these should be separate.  

Some minor things:
- In oozie-site, when it says "Supported values are: simple | kerberos | 
#AUTHENTICATION_HANDLER_CLASSNAME#" that should be "AUTHENTICATOR_CLASSNAME#", 
right?
- It would be useful to add a Log message saying which authenticator type got 
loaded; its in a static block, so it should happen once only
- The new property should also be added to oozie-default.xml
- Can you update the docs with the new property?  It currently says:
{noformat}
Oozie HA works with the existing Oozie security framework and settings. For log 
streaming to work properly in a secure setup oozie.authentication.type must be 
set properly on each server (though this is already required if using security 
in the first place).
{noformat}
which needs to be reworded and updated.

> Currently conf "oozie.authentication.type" is used by specify authentication 
> type for client-server as well as server-server.
> Client-server and server-server communication can use different type of

> We need to have  different conf "oozie.server.authentication.type" to specify 
> server-server authentication type.
