Sergey Shelukhin commented on HIVE-12856: ----------------------------------------- The errors are due to issues in one of the blocking patches that were already fixed in that jira. I think I'll just wait until the two blocking JIRAs are committed. > LLAP: update (add/remove) the UDFs available in LLAP when they are changed > (refresh periodically) > ------------------------------------------------------------------------------------------------- > > Key: HIVE-12856 > URL: https://issues.apache.org/jira/browse/HIVE-12856 > Project: Hive > Issue Type: Sub-task > Reporter: Sergey Shelukhin > Assignee: Sergey Shelukhin > Attachments: HIVE-12856.nogen.patch, HIVE-12856.patch > > > I don't think re-querying the functions is going to scale, and the sessions > obviously cannot notify all LLAP clusters of every change. We should add > global versioning to metastore functions to track changes, and then possibly > add a notification mechanism, potentially thru ZK to avoid overloading the > metastore itself. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
