Brandon Williams commented on CASSANDRA-19495: ---------------------------------------------- bq. If the first node goes down for a second time and time span between the first time it stopped and the second time it stopped is more than the max_hint_window then the hint is not recorded >From the NEWS.txt entry: bq. if a node is not down longer than max_hint_window_in_ms, there is an additional check to see if there is a hint to be delivered which is older than max_window_in_ms. If there is, a hint is not persisted. Is this happening in your case? > Hints not stored after node goes down for the second time > --------------------------------------------------------- > > Key: CASSANDRA-19495 > URL: https://issues.apache.org/jira/browse/CASSANDRA-19495 > Project: Cassandra > Issue Type: Bug > Components: Consistency/Hints > Reporter: Paul Chandler > Priority: Normal > Fix For: 4.1.x, 5.0.x, 5.x > > > I have a scenario where a node goes down, hints are recorded on the second > node and replayed, as expected.
