> CloseCommand gets picked up via datanode by the Hearbeat response it receives
> from SCM. It may happen, one of the follower node not yet received the
> heartBeat response from SCM whereas the leader has got issued the
> closeContainer Command encoded from its own HeartBeat response from SCM. In
> such a case, leader will close the container followed by the followers.
> The follower on which the container is closed Via ratis, has not yet received
> any CloseContainer command from SCM directly and hence on that
> closeCommandHandler is not invoked yet. hence the assertion on the below code
> in one of the followers:
> {code:java}
> if (!containerData.isOpen()) {
> // make sure the closeContainerHandler on the Datanode is invoked
> Assert.assertTrue(
> datanodeService.getDatanodeStateMachine().getCommandDispatcher()
> .getCloseContainerHandler().getInvocationCount() > 0);
> return true;
> }{code}
