[Building Sakai] quartz errors/clustered set up

[Kenwrick Chan]

Folks,
I've set
org.quartz.jobStore.isClustered = true
in
source .. ./scheduler-component-shared/src/java/org/sakaiproject/ 
component/app/scheduler/quartz.properties

and redeployed.  Is there anything that needs to be done to get quartz  
to work in a clustered setting?

I'm getting .
