stack commented on HBASE-21745:
-------------------------------
Nice writeup [~wchevreuil]. Taking a look at the refguide, we should at least
mention healthy meta == healthy upgrade. I can add a note...
Looking at tool, I like how it is basic. Could do w/ a few comments explaining
what its up to (smile). It is reading a text file or what format? Might want to
ensure no assigning is going on concurrently. It is editing the meta directly?
If so, that will not go well out in the field I'd say in anything but the most
controlled of circumstance. Queue a procedure instead?
Good on you W.
