Then I realized it is only a maximum value, and Hive does exponential backoff: 
https://github.com/apache/hive/blob/7b3ecf617a6d46f48a3b6f77e0339fd4ad95a420/ql/src/java/org/apache/hadoop/hive/ql/lockmgr/DbLockManager.java#L95-L97

I think it would be reasonable for us as well, so I switched to a backoff logic.
