      Description

      Access Control: when processes try to read from the column groups, Zebra should be able to handle allowed vs. disallowed user/application accesses. The security is eventuallt granted by corresponding HDFS security of the data stored.

      Expected behavior when column group permissions are set:

      When user selects only columns that they do not have permissions to access, Zebra should return error with message "Error #: Permission denied for accessing column <column name or names>

      Access control applies to an entire column group, so all columns in a column group have same permissions.
