             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.
