Zhe Zhang commented on HDFS-6971:
---------------------------------
The {{ValueQueue}} ({{encKeyVersionQueue}}) uses an underlying cache
{{keyQueues}}, which is constructed with {{expireAfterAccess}} too. I'll add a
test in {{TestKMS}} to verify the time-boundedness.
> Bounded staleness of EDEK caches on the NN

> Key: HDFS-6971
> URL: https://issues.apache.org/jira/browse/HDFS-6971
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: encryption
> Affects Versions: 2.5.0
> Reporter: Andrew Wang
> Assignee: Zhe Zhang

> The EDEK cache on the NN can hold onto keys after the admin has rolled the
> key. It'd be good to time-bound the caches, perhaps also providing an
> explicit "flush" command.
