-----------------------------------------------
Oh, I forgot to increase the resource class for the multiplexer
(CASSANDRA-17043), here are the right runs:

> Replica failure causes timeout on multi-DC write
> ------------------------------------------------
>
> Key: CASSANDRA-16334
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16334
> Project: Cassandra
> Issue Type: Bug
> Components: Consistency/Coordination, Messaging/Internode
> Reporter: Paulo Motta
> Assignee: Aleksandr Sorokoumov
> Priority: Normal
> Fix For: 3.0.x, 3.11.x, 4.0.x, 4.x
>
> Time Spent: 1h
> Remaining Estimate: 0h
>
> Inserting a mutation larger than {{max_mutation_size_in_kb}} correctly throws
> a write error on a single DC keyspace with RF=3:
> {noformat}
> cassandra.WriteFailure: Error from server: code=1500 [Replica(s) failed to
> execute write] message="Operation failed - received 0 responses and 3
> failures: UNKNOWN from /127.0.0.3:7000, UNKNOWN from /127.0.0.2:7000, UNKNOWN
> from /127.0.0.1:7000" info={'consistency': 'LOCAL_ONE', 'required_responses':
> 1, 'received_responses': 0, 'failures': 3}
> {noformat}
> The same insert wrongly causes a timeout on a keyspace with 2 dcs (RF=3 each):
> {noformat}
> cassandra.WriteTimeout: Error from server: code=1100 [Coordinator node timed
> out waiting for replica nodes' responses] message="Operation timed out -
> received only 0 responses." info={'consistency': 'LOCAL_ONE',
> 'required_responses': 1, 'received_responses': 0}
> {noformat}
> Reproduction steps:
> {noformat}
> # Setup cluster
> ccm create -n 3:3 test
> for i in {1..6}; do echo 'max_mutation_size_in_kb: 1000' >>
> ~/.ccm/test/node$i/conf/cassandra.yaml; done
> ccm start
> # Create schema
> ccm node1 cqlsh
> CREATE KEYSPACE test WITH replication = {'class': 'NetworkTopologyStrategy',
> 'dc1': 3, 'dc2': 3};
> CREATE TABLE test.test (key int PRIMARY KEY, val blob);
> exit;
> # Insert data
> python
> from cassandra.cluster import Cluster
> cluster = Cluster()
> session = cluster.connect('test')
> blob = f = open("2mbBlob", "rb").read().hex()
> session.execute("INSERT INTO test (key, val) VALUES (1, textAsBlob('" + blob
> + "'))")
> {noformat}
> Reproduced in 3.0, 3.11, 4.0, trunk.
