How to restart just the TaskTracker on a node

How does one restart just the TaskTracker on a MapR node?

I had installed some new jar files, and wanted the restart to get them into the TT's classpath.

The hadoop-daemon.sh script does not work because it seems that MapR does not cause a pid file to get dropped in the correct place.

I have moved on by simply issuing a kill command, and warden restarts the TT appropriately.  Still, it seems that there should be a more graceful way to do this.
