[jira] [Updated] (YARN-2750) Allow StateMachine has callback when transition fail

     [ https://issues.apache.org/jira/browse/YARN-2750?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jeff Zhang updated YARN-2750:
-----------------------------
    Description: We have a situation that sometimes Transition may fail, but we don't want to handle the fail in each Transition, we'd like to handle it in one centralized place, Allow StateMachine has a callback would be good for us.
