-------------------------------------

             Summary: TaskExecutorService can reject work even if capacity is 
available
                 Key: HIVE-11687
                 URL: https://issues.apache.org/jira/browse/HIVE-11687
             Project: Hive
          Issue Type: Sub-task
    Affects Versions: llap
            Reporter: Siddharth Seth
             Fix For: llap


The waitQueue has a fixed capacity - which is the wait queue size. Addition of 
new work doe snot factor in the capacity available to execute work. This ends 
up being left to the race between work getting scheduled for execution and 
added to the waitQueue.
