* sequence.
* <p>
* 1. We shutdown the network ports.
* <p>
* 2. Now we need to wait for all requests in-flight to finish.
* <p>
* 3. The container manager lock is a read-write lock with "Fairness"
* enabled.
* <p>
* 4. This means that the waiting threads are served in a "first-come-first
* -served" manner. Please note that this applies to waiting threads only.
* <p>
* 5. Since write locks are exclusive, if we are waiting to get a lock it
* implies that we are waiting for in-flight operations to complete.
* <p>
* 6. if there are other write operations waiting on the reader-writer lock,
* fairness guarantees that they will proceed before the shutdown lock
* request.
* <p>
* 7. Since all operations either take a reader or writer lock of container
* manager, we are guaranteed that we are the last operation since we have
* closed the network port, and we wait until close is successful.
* <p>
* 8. We take the writer lock and call shutdown on each of the managers in
* reverse order. That is chunkManager, keyManager and containerManager is
* shutdown.
* Stop Container Service on the datanode.
