Chao Wang updated PIG-987:
--------------------------


I ran into the same issue also.

I did a fresh checkout from apache trunk and ran "ant test", there are 14 test 
cases failed.

Actually, they are caused by some incompatible exception type between pig and 
zebra. It seems pig already moved on with the change (IOException changed to 
IndexOutofBoundException), but zebra is behind a bit in this.

> 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.
