getAttempt Method

getAttempt(): ApplicationAttemptInfo

getAttempt requests the UIRoot for the application info (given the appId) and finds the attemptId among the available attempts.

Note	appId and attemptId are path parameters.

In the end, getAttempt returns the ApplicationAttemptInfo if available or reports a NotFoundException:

unknown app [appId], attempt [attemptId]
