-----------------------------------------
Summary: 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
I have a scenario where a node goes down, hints are recorded on the second node
and replayed, as expected. 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, no hint file is
created, and the mutation never arrives at the node after it comes up again.
I have debugged this and it appears to due to the way hint window is persisted
after https://issues.apache.org/jira/browse/CASSANDRA-14309
The code here:
[https://github.com/apache/cassandra/blame/cassandra-4.1/src/java/org/apache/cassandra/service/StorageProxy.java#L2402]
uses the time stored in the HintsBuffer.earliestHintByHost map. This map is
based on the UUID of the host, but this does not seem to be cleared when the
node is back up, and I think this is what is causing the problem.
