--------------------------------------

             Summary: 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
            Reporter: maxwellguo


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.
