>                 URL: https://issues.apache.org/jira/browse/HADOOP-11218
>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: kms
>    Affects Versions: 2.7.0
>            Reporter: Robert Kanter
>            Priority: Critical
>
> HADOOP-11217 required us to specifically list the versions of TLS that KMS 
> supports. With Hadoop 2.7 dropping support for Java 6 and Java 7 supporting 
> TLSv1.1 and TLSv1.2, we should add them to the list.
