Hints not delivered possibly because of pagination issue
--------------------------------------------------------
Key: CASSANDRA-3935
URL: https://issues.apache.org/jira/browse/CASSANDRA-3935
Project: Cassandra
Issue Type: Bug
Affects Versions: 1.1.0
Reporter: B. Todd Burruss
I'm testing hinted handoff in 1.1 beta1 and cannot seem to get a hint
delivered. 3 node cluster, RF = 3, writing with CL = ONE. killed a host then
did the write using the CLI on another node. I can see hint waiting using CLI
and I see the log messages at the end of this email. this suggests the hints
exist bu are not being delivered (and I'll see the log messages over and over.)
I did see tracing with debugger and see that in
HintedHandoffManager.deliverHintsToEndpointInternal, this line will remove the
hint because of the Integer.MAX_VALUE
ColumnFamily hintsPage =
ColumnFamilyStore.removeDeleted(hintStore.getColumnFamily(filter),
Integer.MAX_VALUE);
I'm not sure I quite understand while MAX is used when the same "remove" is
done in getColumnFamily(filter). regardless if it is useful or not, it
prevents the hints from delivery.
any thoughts?
