Description

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  can not work with Java-9 modules.

 

So we should do something to stop reuse the package name of original hadoop.
