[jira] [Commented] (AMBARI-7542) START/STOP should be standart
commands for all components
[ https://issues.apache.org/jira/browse/AMBARI-7542?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14152638#comment-14152638 ]
Sumit Mohanty commented on AMBARI-7542:
---------------------------------------
[~dmitriusan], if it is allowed to issue START and STOP as custom commands then will they not skip the state machines? Also, if a START command is issued against multiple component types then is it still guaranteed that the role command order will be followed?
