[ https://issues.apache.org/jira/browse/HDFS-14413?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16923603#comment-16923603 ]

Upload draft patch v001
# Add two options (numTotalNameNodes and in numTotalJournalNodes) in CLI, so user can run more than two NN and 3 JN, but required NodeManager >= max(JN,NN), because JN or NN can't run on same machine
# Add ZKFC so if one NN die in a container, other SNN would be active soon, but it required user *specify ha.zookeeper.quorum* and *dfs.ha.fencing.ssh.private-key-files* in Dynamometer config
# Fix some checkstyle error
I will add Unit test in next patch.
