Vijay commented on CASSANDRA-4554:
----------------------------------

Just to clarify kind of lost, 
We are good with 0001 initially submitted and we can just ignore 0002?

I'm not a fan of switching hints-in-progress to a Cache
{quote}
makeComputingMap is deprecated[1] hence made the cache, i can remove that from this patch,
let me know.

> We know that we need to repair whenever we lose a node or disk permanently (since it
may have had undelivered hints on it), but without exposing this we don't know when nodes
stop saving hints for a temporarily dead node, unless we're paying very close attention to
external monitoring.
