> When I using the REST API of the AHS to get a running app's latest attempt
> id, it always returns a invalid id like
> *appattempt_1516873125047_0013_{color:#FF0000}-000001{color}*.
> But when the app is finished, the RM will push a finished event which
> contains the latest attempt id to TimelineServer, so the id will transitive
> to a correct one in the end of the application.
> I think as the app is running, this value should be a correct one, so I add
> the latest attempt id in the other info of the app's entity when the app
> trans to RUNNING state. Then the AHS will use this value to set the
> currentAppAttemptId.
