Github user mjwall commented on the issue:
    @ShawnWalker I reviewed this and talked with @keith-turner some.  I imagine during a rolling
upgrade the process would be.
    - Stage the new install on the box
    - Run
    - Reconfigure the node to use the new install
    - Run
    The command has the master unload the tablets I think.  How will this patch
handle that case?
    When a tablet server is suspended, all queries will block right?  I see you are suspending
the metadata tablets too.  That will affect more than just a user queries though.  Bulk imports
trying to get hosted locations comes to mind.  I see you are not suspending the root tablet
    I see you are storing the host and port in the metadata for a suspended tablet.  Sometimes
we have tservers come up with a different host or port.  In that case, I guess the tablets
will wait until the suspend duration to be reassigned.
