Description

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
