> Currently there is no direct way to get the exact reason as to why a 
> submitted app is still in ACCEPTED state. It should be possible to know 
> through RM REST API as to what aspect is not being met - say, queue limits 
> being reached, or core/ memory requirement not being met, or AM limit being 
> reached, etc.
