             Summary: Status commands temporary break host component state machine
                 Key: AMBARI-15202
                 URL: https://issues.apache.org/jira/browse/AMBARI-15202
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 1.6.0
            Reporter: Myroslav Papirkovskyy
            Assignee: Myroslav Papirkovskyy
            Priority: Critical
             Fix For: 2.2.2


This occurs when status command response is received after start of next stage which modifies sch state (quite often on starting services during install).

# status command is sent to agent (happens every 60 seconds)
# start commands are scheduled, generated event which move sch from INSTALLED to STARTING
# status command response received from agent. sch status directly set to INSTALLED bypassing state machine
# All subsequent task reports from agent trigger InvalidTransitionException, as OP_INPROGRESS event tries to do STARTING -> STARTING transition.
# However at task end we support INSTALLED -> STARTED transition for STARTED event. So tasks finish normally.
