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

    [ https://issues.apache.org/jira/browse/HIVE-17008?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16101019#comment-16101019

Dan Burkert commented on HIVE-17008:
------------------------------------

[~akolb] I'm playing around with a fix [here|https://github.com/danburkert/hive/commit/e8b2527ae0fbdff1df2a3b102cba1e0c3cd89e4b?w=1],
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.
