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

             Summary: testCountDownLatch can be null in PartitionerDecorator 
depending on user's injection controls config
                 Key: DRILL-6124
                 URL: https://issues.apache.org/jira/browse/DRILL-6124
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Timothy Farkas
            Assignee: Timothy Farkas


In PartitionerDecorator we get a latch from the injector with the following 
code.

testCountDownLatch = injector.getLatch(context.getExecutionControls(), 
"partitioner-sender-latch");

However, if there is no injection site defined in the user's drill 
configuration then testCountDownLatch will be null. So we have to check if it 
is null in order to avoid NPE's
