> Easier way to simulate the issue:
> 1. Start hive cli with "--hiveconf hive.execution.mode=llap"
> 2. Run a sql script file (e.g sql script containing tpc-ds queries)
> 3. In the middle of the run, press "ctrl+C" which would interrupt the current job. This
should not exit the hive cli yet.
> 4. After sometime, launch the same SQL script in same cli. This would get stuck indefinitely
(waiting for computing the splits).
> Even when cli is quit, AM runs forever until explicitly killed. 
> Issue seems to be around {{LlapTaskSchedulerService::schedulePendingTasks}} dealing with
the loop when it encounters {{DELAYED_RESOURCES}} on task scheduling.
