We are running HDP2.3.4 cluster at Enterprise Level and
around 5 BI Business Units are connecting to the Hadoop cluster.
They are creating tables and importing files using Hive Views & HDFS Files View but here every BI Business unit is viewing
others tables( I mean only table names and not the data) in hive views and data
directories on HDFS as well(level 1 directory or root directory)
Based on Linux permission & Linux group policies we implemented access control mechanism
on table’s data & sub directories but we are not able to hide table names
and parent directories(level 1 directory) in HDFS.
