----------------------------------------
[~rajesh.balamohan], this sounds related to HIVE-15467?
> LLAP: TaskSchedulerService can get stuck when scheduleTask returns
> DELAYED_RESOURCES
> ------------------------------------------------------------------------------------
>
> Key: HIVE-15529
> URL: https://issues.apache.org/jira/browse/HIVE-15529
> Project: Hive
> Issue Type: Bug
> Components: llap
> Reporter: Rajesh Balamohan
> Priority: Critical
>
> 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.
