-----------------------------------
Component/s: Local/Other
> Add disk failure policy for hint/cache
> ---------------------------------------
>
> Key: CASSANDRA-15404
> URL: https://issues.apache.org/jira/browse/CASSANDRA-15404
> Project: Cassandra
> Issue Type: Improvement
> Components: Local/Config, Local/Other
> Reporter: maxwellguo
> Priority: Normal
>
> 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/cache'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/cache's disk_faily_policy should be separately. So we can got
> three type of
> disk faily policy for : data disk , commitlog disk and hint/cache 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.
