Chaoyu Tang commented on HIVE-16334: ------------------------------------ LGTM, +1 > Query lock contains the query string, which can cause OOM on ZooKeeper > ---------------------------------------------------------------------- > > Key: HIVE-16334 > URL: https://issues.apache.org/jira/browse/HIVE-16334 > Project: Hive > Issue Type: Improvement > Components: Locking > Reporter: Peter Vary > Assignee: Peter Vary > Attachments: HIVE-16334.2.patch, HIVE-16334.3.patch, > HIVE-16334.4.patch, HIVE-16334.patch > > > When there are big number of partitions in a query this will result in a huge > number of locks on ZooKeeper. Since the query object contains the whole query > string this might cause serious memory pressure on the ZooKeeper services. > It would be good to have the possibility to truncate the query strings that > are written into the locks -- This message was sent by Atlassian JIRA (v6.3.15#6346)
