Description

In HDDS-1383, we introduce a new upgrade command for supporting to in-place upgrade from HDFS to Ozone.

upgrade       HDFS to Ozone in-place upgrade tool
....
Usage: ozone upgrade [-hV] [--verbose] [-conf=<configurationPath>]
                     [-D=<String=String>]... [COMMAND]
Convert raw HDFS data to Ozone data without data movement.
      --verbose   More verbose output. Show the stack trace of the errors.
      -conf=<configurationPath>

  -D, --set=<String=String>

  -h, --help      Show this help message and exit.
  -V, --version   Print version information and exit.
Commands:
  plan     Plan existing HDFS block distribution and give.estimation.
  balance  Move the HDFS blocks for a better distribution usage.
  execute  Start/restart upgrade from HDFS to Ozone cluster.

[hdfs@lyq ~]$ ~/ozone/bin/ozone upgrade plan
[In-Place upgrade : plan] is not yet supported.
[hdfs@lyq ~]$ ~/ozone/bin/ozone upgrade balance
[In-Place upgrade : balance] is not yet supported.
[hdfs@lyq ~]$ ~/ozone/bin/ozone upgrade execute
In-Place upgrade : execute] is not yet supported

But this feature has not been implemented yet and is a very big feature. 
I don't think it's good to expose a cli command that is not supported and meanwhile that cannot be quickly implemented in the short term.
