We are currently using Sentry cdh5-1.5.1_5.7.2 and matching CDH Hadoop. When we evaluated newer versions of Hadoop, we noticed that the interface / class (such as AuthorizationProvider and DefaultAuthorizationProvider) required by Sentry HDFS plugin, do not exist outside of CDH Hadoop.
Investigating a bit further, we found the original issue ( https://issues.apache.org/jira/browse/HDFS-6826), design doc ( https://issues.apache.org/jira/secure/attachment/12662011/HDFSPluggableAuthorizationProposal-v2.pdf) and commit that introduced those classes 2.5 years ago. Our question: is there a plan to port those interfaces / classes to Apache Hadoop? Thanks Qianbo Huai Uber Data Infra
