Flavio Junqueira commented on BOOKKEEPER-272:
---------------------------------------------
bq. I think we should keep it in the bookie process and enabled by default
I've expressed this concern before that I don't understand completely the use
cases for the auditor. Short-lived ledgers will not need it because the window
of vulnerability is narrow. In my mind the auditor is mainly for use cases that
require long-lived ledgers. What's the rationale for having it enabled by
default?
bq. There's no strong requirement for it, and it just confuses matters.
It confuses matters to mix both. BookKeeper provides a set of guarantees, and
the auditor complements that set of properties by healing the replica set of
under-replicated ledgers. The auditor also does not provide any functionality
in the critical path of BookKeeper client calls. Given these two observations,
it makes more sense to me to keep it separated. It makes it simpler to reason
about what the system is doing and may avoid undesirable interferences.

> The idea is to build automatic mechanism to find out the bookie failures.
> Setup the bookie failure notifications to start the re-replication process.
> There are multiple approaches to findout bookie failures. Please refer the
