Subru Krishnan commented on YARN-6996:
--------------------------------------
Thanks [~rchiang] for bringing this up. We had looked at jsr
[license|https://github.com/jsr107/jsr107spec/blob/master/LICENSE.txt] and
looks like even though they have Apache 2.0, they have not updated their
release yet.
The patch itself LGTM, only a minor comment (as [~busbey] pointed out) - we
need to update the Hadoop LICENSE.txt accordingly.

> Key: YARN-6996
> URL: https://issues.apache.org/jira/browse/YARN-6996
> Project: Hadoop YARN
> Issue Type: Bug
> Affects Versions: 3.0.0-beta1
> Reporter: Ray Chiang
> Assignee: Ray Chiang
> Attachments: YARN-6996.001.patch

> With YARN Federation, we added YARN-3672, which adds the following to
> {noformat}
> <groupId>javax.cache</groupId>
> <artifactId>cache-api</artifactId>
> {noformat}
> This third-party library has some murky license history, as documented in
> this [really long comment
> thread|https://github.com/jsr107/jsr107spec/issues/333]. The summary of the
> thread is that "the library is officially APL (take our word for it), but
> there hasn't been a subsequent release with the license file change".
> LEGAL-325 has been filed to discuss the validity of this license for Apache.
> Before we get to final Hadoop 3 release, I'm wondering if anyone else has
> concerns about using this library. Just from looking at the various javax
> Maven artifacts in our pom.xml files, I see a lot of other javax.* library
> entries (although we may not ship the .jars if they're part of the Java
> runtime).
