Example 9 with ApplicationInstance

use of com.yahoo.vespa.applicationmodel.ApplicationInstance in project vespa by vespa-engine.

the class OrchestratorImpl method resume.

@Override

        * When making a state transition to this state, we have to consider that if the host has been in
        * ALLOWED_TO_BE_DOWN state, services on the host may recently have been stopped (and, presumably, started).
        * Service monitoring may not have had enough time to detect that services were stopped,
        * and may therefore mistakenly report services as up, even if they still haven't initialized and
        * are not yet ready for serving. Erroneously reporting both host and services as up causes a race
        * where services on other hosts may be stopped prematurely. A delay here ensures that service
        * monitoring will have had time to catch up. Since we don't want do the delay with the lock held,
        * and the host status service's locking functionality does not support something like condition
        * variables or Object.wait(), we break out here, releasing the lock before delaying.
