Hi Lune, Can you try by removing the postScannerFilterRow from the RangerAuthorizationCoprocessor class( https://github.com/apache/ranger/blob/master/ranger-hbase-plugin-shim/src/main/java/org/apache/ranger/authorization/hbase/RangerAuthorizationCoprocessor.java#L1772 ).
Please let me know if it works for you.
