>                 Key: HADOOP-14688
>                 URL: https://issues.apache.org/jira/browse/HADOOP-14688
>             Project: Hadoop Common
>          Issue Type: Improvement
>          Components: kms
>            Reporter: Xiao Chen
>            Assignee: Xiao Chen
>         Attachments: GC root of the String.png, HADOOP-14688.01.patch, heapdump analysis.png,
> This is inspired by [~misha@cloudera.com]'s work on HDFS-11383.
> The key names and key version names are usually the same for a bunch of {{KeyVersion}}
and {{EncryptedKeyVersion}}. 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.
