This fix will appear to the 4.0.0 release. If someone wants to see this fix in other releases then it should be backported to appropriate branches. See: https://cwiki.apache.org/confluence/display/Hive/Hive+PreCommit+Patch+Testing <https://cwiki.apache.org/confluence/display/Hive/Hive+PreCommit+Patch+Testing> https://cwiki.apache.org/confluence/display/Hive/HowToContribute <https://cwiki.apache.org/confluence/display/Hive/HowToContribute> https://cwiki.apache.org/confluence/display/Hive/HowToContribute#HowToContribute-UnderstandingHiveBranches <https://cwiki.apache.org/confluence/display/Hive/HowToContribute#HowToContribute-UnderstandingHiveBranches> > 2) The patch doesn't appear to include documentation. Perhaps is that why it > hasn't yet been added to an official release? https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties <https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties> should contain all of the configs, even unreleased ones. Lefty was the one who kept nagging us to update the documentation, since she left we often forget to do it. If you find such a case you can ask for wiki edit rights, and fix the doc, or ask the owner of the jira > 3) I haven't been able to directly test this feature yet, so I wanted to get > some clarity: With this change (and with the property set to 'false'), I > assume that Hive will pass the full principal name in the "doAs" parameter to > other kerberized services (e.g. HDFS) instead of just the short name, is that > correct? Could you describe how exactly this will affect Hive's behavior? AFAIK this does not effect HDFS - this fix is for Ranger related problems > Thanks a lot, > > Julien
