Yan Zhou commented on PIG-987: ------------------------------ I have attached a new patch that removes the use of lzo in 6 test scripts. Accordingly, patches of 2 "downstream" Jiras, PIG-986 and PIG-992, will also be updated; while the other three "downstream" patches, PIG-991, PIG-993 and PIG-944, need not to be changed. > [zebra] Zebra Column Group Access Control > ----------------------------------------- > > Key: PIG-987 > URL: https://issues.apache.org/jira/browse/PIG-987 > Project: Pig > Issue Type: New Feature > Affects Versions: 0.6.0 > Reporter: Yan Zhou > Assignee: Yan Zhou > Attachments: ColumnGroupSecurity.patch, ColumnGroupSecurity.patch, > TEST-org.apache.hadoop.zebra.mapred.TestCheckin.txt > > > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
