If your hint directory is not writable, this doesn't sound good anyways.
Unfortunately, there's no good way to distinguish between all errors that were
caused by concurrent processes, user error, filesystem corruption, and hardware
failures. We do apply one policy right now, and I still think that having
separate policies for every directory might be overconfiguration.

This sounds like a minor inconvenience. Moreover, if your hint directory is not
writable, this doesn't sound good anyways. Unfortunately, there's no good way
to distinguish between all errors that were caused by concurrent processes,

> I use the default config to do some test. I delete all hint directory by
> mistake，but my cassandra process at last stoped .Latter I found that that is
> because the hint directory use the data disk policy .
> In our production cluster , hint and cache's dir are set separately and are
> not the same with data dir . And we know that cassandra can use multi data
> directory to store data, the hint's data operation should not affect the data
> and commitlog 's read or write . Also
> hint/cache 's data loss do not affect the cassandra's correct read .
> so I think hint's disk_faily_policy should be separately. So we can got three
> type of
> disk faily policy for : data disk , commitlog disk and hint disk 。
> I don't know if my suggestion is meaningful. If it is, I would like to take
> over the issue。I'm also happy to receive new suggestions.
> I thinks this is a bug , but now I can not modify the Type of the issue .
> The situation is easy to reproduce .The data disk policy use stop . every
> time you delete the hint directory will cause the daemon's stop.Stop
> NativeTransport server and gossip .
