Hello Patel. Thanks for this first answer.
May you tell me more about what this method do, please ? I can find the class you mentioned in the following jar : ranger-hbase-plugin-0.7.0.2.6.2.0-205.jar So it means I need to recompile the whole jar with the modification you advise, right ? As I use the complete stack HDP 2.6.2 of Cloudera, do you know if there is some documentation to do this recompilation (which dependencies to use for example) ? Best regards.
