Colin Patrick McCabe commented on HDFS-5636: -------------------------------------------- It might better to leave existing cache directives as-is, similar to how setting a quota or changing permissions doesn't undo things done in the past. Aside from that, looks reasonable. > Enforce a max TTL per cache pool > -------------------------------- > > Key: HDFS-5636 > URL: https://issues.apache.org/jira/browse/HDFS-5636 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: caching, namenode > Affects Versions: 3.0.0 > Reporter: Andrew Wang > Assignee: Andrew Wang > > It'd be nice for administrators to be able to specify a maximum TTL for > directives in a cache pool.
