Subject [jira] [Commented] (HIVE-17008) DbNotificationListener should skip failed events
Date Wed, 26 Jul 2017 00:58:00 GMT


Dan Burkert commented on HIVE-17008:

[~akolb] I'm playing around with a fix [here|],
but it doesn't appear to work quite correctly.  It's fine with me if someone else wants to
jump on this an assign it to themselves; I think it should be a high priority bug.

> When dropping a non-existent database, the HMS will still fire registered {{DROP_DATABASE}}
event listeners.  This results in an NPE when the listeners attempt to deref the {{null}}
database parameter.
