>                 Key: RANGER-3639
>                 URL: https://issues.apache.org/jira/browse/RANGER-3639
>             Project: Ranger
>          Issue Type: Improvement
>          Components: kms
>    Affects Versions: 3.0.0, 2.2.0, 2.3.0
>            Reporter: kirby zhou
>            Priority: Major
>
> Now, ranger-kms have some conflict packages with hadoop.
> org.apache.hadoop.crypto.key
> org.apache.hadoop.crypto.key.kms.server
>  
> It is caused by some historical reason.
> For example:
> Copied code from hadoop-kms, 
> Want to use protected method such as Metadata().
>  
> But it also creates some problems:
> 1. Developers need to be careful with files with duplicate names. such as:  KMSAcls.java
> [https://github.com/apache/hadoop/tree/trunk/hadoop-common-project/hadoop-kms/src/main/java/org/apache/hadoop/crypto/key/kms/server]
> 2. Sometime runtime conflict happens.
> 3. [split package|https://blog.codefx.org/java/java-9-migration-guide/#Split-Packages]  can not work with Java-9 modules.
>  
> So we should do something to stop reuse the package name of original hadoop.
