Hi, We are evaluating Ranger for authorization over our existing hadoop cluster.Had some doubts: - I wonder , is ranger auth a substitute of HDFS authorization (FSPermissionChecker) or a layer above it? - Layer above. - If the hdfs and ranger rules are conflicting, eg: ranger allows but hdfs denies, which rule will be used? - Ranger rules imposed. - Does Ranger work with NN federation? - Yes I was going through many articles but was unable to get these answers,it would be great if someone can help me here. Thanks in advance,Ravi
