Brandon Williams commented on CASSANDRA-16815:
----------------------------------------------
bq. 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).
Are you talking about replacement outside of replace_address? Meaning the node
has been decommissioned or removeded? Because replace_address should keep the
same host_id so that it receives any hints.

> Host replacement is possible to produce orphaned hints files that the
> original associated host ID no longer exist in the cluster (i.e., being

> 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.
