These are defined in role_command_order.json. If there is no dependency for the component it can run in parallel between the nodes. However in a particular node the execution will be sequential.</P><P>You can check the role_command_order.json for different services and their dependencies. Just run the command in ambari server to find all the json files.</P><PRE>find /var/lib/ambari-server/ -iname role_command_order.json</PRE><P>Thanks,</P><P>Aditya</P> Tue, 05 Dec 2017 01:09:28 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/how-to-enable-stop-services-in-parallel/m-p/215809#M72224 asirna 2017-12-05T01:09:28Z
