Yifan Cai commented on CASSANDRA-16815:
---------------------------------------
[~brandon.williams], general replacement, as long as not replacing with the
same address. In this case, the new (replacing) node gets a new host ID. The
change was added in CASSANDRA-8523.
> Background schedule to clean up orphaned hints files

> Host replacement is possible to produce orphaned hints files that the
> original associated host ID no longer exist in the cluster (i.e., being
> replaced). Those orphaned hints files will not be dispatched and only
> consumes up the disk space.
> We can have a background schedule that infrequently checks and deletes the
> files if they are orphaned and have exceeded the TTL.
