You can set http://hadoop.apache.org/docs/current/api/org/apache/hadoop/yarn/api/records/ApplicationSubmissionContext.html#setMaxAppAttempts(int) to 0, at a per-app level, to prevent any reattempts/recovery of your AM.
For a cluster-wide effect instead, you can limit by overriding the default value of the RM property yarn.resourcemanager.am.max-retries in the RM's YarnConfiguration or yarn-site.xml.
