Kent Yao commented on RANGER-2128:
----------------------------------
[~bosco] I had a quick look on SPARK-18127 and its related PR. It has exposed
Parser/Analyzer/Optimizer/Planner, which is so great for all users. It also
makes it easier for users to call our plug-in.
Some existing issues may be considered before we start
1. spark-authorizer is designed as a Optimize Rule for Spark SQL and executed
after all other default rules because rules, such as column pruning, projection
push down, and so on, should be operated first.
2. spark-authorizer has to visit hive SessionState object which is not
accessible for spark context classloader because Spark use a isolated
classloader to load hive client jars.
2.1 spark-authorizer itself will rewrite SessionState object the first time
to do privileges checking
2.2 kyuubi hacks spark and turn off that classloader.
3. spark-authorizer reuses the ranger hive plugin(0.5）which contains
incompatible jersey dependencies with spark ones.
And what are the steps I should follow to contribute Ranger?
Thanks
