> App submission involves
> 1) creating appId
> 2) using that appId to submit an ApplicationSubmissionContext to the user.
> The client may have obtained an appId from an RM, the RM may have failed over, and the
client may submit the app to the new RM.
> Since the new RM has a different notion of cluster timestamp (used to create app id)
the new RM may reject the app submission resulting in unexpected failure on the client side.
> The same may happen for other 2 step client API operations.
