- * Stops the ozone container.

- * Shutdown logic is not very obvious from the following code. if you need to
- * modify the logic, please keep these comments in mind. Here is the shutdown
- * 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.
+ * Build's container map.
