Tested both of the following commands worked with this PR on x86_64.

1. Deploy HDFS and Flink simultanously and run Flink's smoke test, which requires HDFS installed:

$ ./docker-hadoop.sh -d -k hdfs,flink -s flink -L -C config_centos-8.yaml -c 1

2. Only deploy Flink, without HDFS:

$ ./docker-hadoop.sh -d -k flink -L -C config_centos-8.yaml -c 1
