kevin su commented on HDFS-14413:
---------------------------------
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 and 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.
