ambari-server/src/main/resources/stacks/HDP/2.2/upgrades/nonrolling-upgrade-2.3.xml
 (line 889)
<https://reviews.apache.org/r/48549/#comment202164>

    hosts="all" is the default, you can remove it.
    sequential="true" isn't needed since it is only useful when two consecutive 
tasks need to run one after the other even though they are on different hosts.
    
    Why is there a stop and start in post-upgrade?
    What are you trying to achieve here?
    
    Pre-upgrade is any steps to execute before restarting the component, 
Post-upgrade is after restarting. So if there are any other stop-start steps, 
it means the component is being restarted twice!
