Larry McCay commented on KNOX-843:
----------------------------------
[~moresandeep] - thank you for the additional review!
I am actually thinking that we should push this out of the 0.13.0 release.
It seems to be a good start but it has raised additional questions in my mind,
in fact.
For instance, any particular service has its own particular HA mode - be it
active-active or active-passive. It shouldn't have to be configured in every
topology to turn on haActive or not. It should be part of the service
definition itself.
Instead of adding this capability to the DefaultHaDispatch, I propose that a
new LoadBalancingHaDispatch be created and that can be selected in the service
definitions for those services that are indeed active-active.
{code}
<dispatch classname="org.apache.hadoop.gateway.ha.dispatch.DefaultHaDispatch"
ha-classname="org.apache.hadoop.gateway.ha.dispatch.LoadBalancingHaDispatch"/>
{code}
This would remove the need to configure it in the topology.
I am going to move this to the 0.14.0 release for now.
If it is seen as critical for 0.13.0 and we can turn it around in a few days
then we can move it back in.
