Subject [jira] [Updated] (HDFS-6971) Bounded staleness of EDEK caches on the NN
Date Fri, 06 Jan 2017 23:40:59 GMT

     [ https://issues.apache.org/jira/browse/HDFS-6971?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andrew Wang updated HDFS-6971:
------------------------------
    Resolution: Duplicate
        Status: Resolved  (was: Patch Available)

I think we can dupe this in favor of HDFS-11210 which will flush the caches on key roll.

> 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.
