Yarn Site XML Changes Require Restarts?

A while back I had another question about Spark Streaming jobs dying after a week: MapR Ticket expiry in spark streaming? 

 

The answer was to override yarn.mapr.ticket.expiration in the yarn-site.xml (which defaults to a week) as shown below.

 

yarn.mapr.ticket.expirationDefault value: 604800000 Default source: code

It doesn't look like it worked.  Do we need to restart any processes on the cluster nodes to make changes to the yarn-site.xml apply to newly scheduled YARN jobs?
