Sijie Guo commented on BOOKKEEPER-387:
--------------------------------------
@surendra, Upgrade just needed to be run when upgrading from 4.0.0 to 4.1.0,
since there is directories layout changes. from 4.1.0 to 4.2.0, there is no
directory layout changes as far now, so you don't need to run upgrade tool.
> BookKeeper Upgrade is not working.
