Sam Tunnicliffe updated CASSANDRA-16246: ---------------------------------------- Status: Changes Suggested (was: Review In Progress) > Unexpected warning "Ignoring Unrecognized strategy option" for > NetworkTopologyStrategy when restarting > ------------------------------------------------------------------------------------------------------ > > Key: CASSANDRA-16246 > URL: https://issues.apache.org/jira/browse/CASSANDRA-16246 > Project: Cassandra > Issue Type: Bug > Components: Observability/Logging > Reporter: Yifan Cai > Assignee: Yifan Cai > Priority: Normal > Fix For: 4.0-beta > > Time Spent: 10m > Remaining Estimate: 0h > > During restarting, bunch of warning messages like > "AbstractReplicationStrategy.java:364 - Ignoring Unrecognized strategy option > {datacenter2} passed to NetworkTopologyStrategy for keyspace > distributed_test_keyspace" are logged. > The warnings are not expected since the mentioned DC exist. > It seems to be caused by the improper order during startup, so that when > opening keyspaces it is unaware of DCs. > The warning can be reproduced using the test below. > {code:java} > @Test > public void testEmitsWarningsForNetworkTopologyStategyConfigOnRestart() > throws Exception { > int nodesPerDc = 2; > try (Cluster cluster = builder().withConfig(c -> c.with(GOSSIP, NETWORK)) > .withRacks(2, 1, nodesPerDc) > .start()) { > cluster.schemaChange("CREATE KEYSPACE " + KEYSPACE + > " WITH replication = {'class': > 'NetworkTopologyStrategy', " + > "'datacenter1' : " + nodesPerDc + ", > 'datacenter2' : " + nodesPerDc + " };"); > cluster.get(2).nodetool("flush"); > System.out.println("Stop node 2 in datacenter 1"); > cluster.get(2).shutdown().get(); > System.out.println("Start node 2 in datacenter 1"); > cluster.get(2).startup(); > List<String> result = cluster.get(2).logs().grep("Ignoring > Unrecognized strategy option \\{datacenter2\\}").getResult(); > Assert.assertFalse(result.isEmpty()); > } > } > {code} -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
