dfsadmin -rollingUpgrade prepare' returned 255. rollingUpgrade: FileSystem wasb://hostname
is not an HDFS file system
Usage: hdfs dfsadmin [-rollingUpgrade [<query|prepare|finalize>]]
{code}

*Fix:*
To fix this issue  we need to explicitly pass "-fs" argument to the all hdfs dfsadmin commands
in the files: journalnode_upgrade.py, namenode_upgrade.py, datanode_upgrade.py, namenode.py

Example: hdfs dfsadmin -fs hdfs://mycluster -rollingUpgrade prepare
