We should not create duplicate > objects for them. > This is more important to HDFS-10899, where we try to re-encrypt all files' > EDEKs in a given EZ. Those EDEKs all has the same key name, and mostly using > no more than a couple of key version names. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
