[jira] [Created] (AURORA-756) startUpdate fails with "Instance count must be positive."

Maxim Khutornenko created AURORA-756:
----------------------------------------

             Summary: startUpdate fails with "Instance count must be positive."
                 Key: AURORA-756
                 URL: https://issues.apache.org/jira/browse/AURORA-756
             Project: Aurora
          Issue Type: Bug
          Components: Scheduler
            Reporter: Maxim Khutornenko


When a noop update is requested (i.e. all instances are already in desired state), the UpdateFactory.newUpdate fails checkArgument validation in:
{noformat}
     checkArgument(
          !instructions.getDesiredState().getInstances().isEmpty(),
          "Instance count must be positive.");
{noformat}

Recommend fixing it with https://reviews.apache.org/r/25481, which replaces that validation with the one in SchedulerThriftInterface before any diff applied.
