----------------------------------
Summary: Ranger KMS should refactor top stop invading java package
of hadoop
Key: RANGER-3639
URL: https://issues.apache.org/jira/browse/RANGER-3639
Project: Ranger
Issue Type: Improvement
Components: kms
Affects Versions: 2.2.0, 3.0.0, 2.3.0
Reporter: kirby zhou
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.
