What are the ideal / Minimum required ACL's that need to be applied on a HDFS directory containing Hive External Tables? 1. I have a directory '/user/devteam/custdata' with permissions 770. hdfs dfs -getfacl /user/devteam/custdata # file: /user/devteam/custdata # owner: devteam # group: devteam user::rwx group::rwx other::--- 2. I set ACL of... hdfs dfs -setfacl -R -m group:hive:rwx,group:qateam:r-x /user/devteam/custdata 3. Sentry Roles create role qateamrole; grant select on database devdb to role qateamrole; create role devteamrole; grant all on database devdb to role devteamrole; grant all on uri '/user/devteam/custdata' to role devteamteamrole; By setting these two permissions with HDFS sentry sync enabled. Will I be able to run all my sqoop jobs and hive queries as the owner and qateam successfully? At the same time I want data to be visible only to the owner and teams that have permissions to query / cat / list them. Thanks
