> In TestHDFSServerPorts.testBackupNodePorts, there are two attempts at starting backup node.
> *Attempt 1*:
> 1) It binds namenode backup address with 0:
> {quote}
> backup_config.set(DFSConfigKeys.DFS_NAMENODE_BACKUP_ADDRESS_KEY, THIS_HOST);
> {quote}
> 2) It sets namenode backup address with an available port X.
> 3) It fails rightfully due to using the same http address as active namenode.
> *Attempt 2*:
> 1) It tries to reuse port X as namenode backup address.
> 2) It fails to bind to X because Windows does not release port X properly after *Attempt 1* fails.
