             Summary: Discuss license issue with javax.cache library
                 Key: HADOOP-14763
                 URL: https://issues.apache.org/jira/browse/HADOOP-14763
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 3.0.0-beta1
            Reporter: Ray Chiang


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).
