[Ghatage]

BUG REPORT

Bookies are allowed tot boot up even if they don't have a cookie in the metadata store.

To Reproduce

Steps to reproduce the behavior in jUnit:

1. Boot up a bookie
2. Delete it's cookie from metadata store
3. Restart bookie
4. Bookie comes back up even without a cookie
5. This is a problem because any following operations on cookies will result in InvalidCookieException

Expected behavior

If for some reason, the bookie does not have a cookie in metadata store it should not be allowed to come up because the cookies are out of sync.
