Darin,
I had also tested the same scenario but I had "maxInstances: 1" in
myriad-config-default.yml for JHS configuration and it didn't start new JHS
instance on RM restart.
Here is my JHS configuration looks like from myriad-config-default.yml:
* taskName: jobhistory*
* serviceOptsName: HADOOP_JOB_HISTORYSERVER_OPTS*
* command: $YARN_HOME/bin/mapred historyserver*
* maxInstances: 1*
