             Summary: Possible Deadlock in Partition Decorator Due To Shared 
ThreadPool With DataTunnel
                 Key: DRILL-6326
                 URL: https://issues.apache.org/jira/browse/DRILL-6326
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Timothy Farkas
            Assignee: Timothy Farkas

The PartitionDecorator uses the DrillbitContext.getExecutor() threadpool for 
threads that send batches to downstream partitions. This threadpool is the same 
threadpool that is used for DataTunnel connections. This shared threadpool 
could cause a deadlock in the event where the number of partitions is greater 
than or equal to the max number of threads in the shared threadpool.
