*API call*:

PUT http://162.216.148.43:8080/api/v1/clusters/c1/services?ServiceInfo/state=INIT

{"RequestInfo": {"context" :"Install Services"}, "Body": {"ServiceInfo": {"state": "INSTALLED"}}}

For every Execution command we are finding out which HostComponents are in Passive state and setting them on the execution command.

org.apache.ambari.server.controller.MaintenanceStateHelper.getMaintenanceHostCompoments(Clusters, Cluster) spent most of the time acquiring locks.
