I've a cluster consisting of 5 cassandra nodes. The cassandra version used is


The keyspace strategy and is defined as follows:

CREATE KEYSPACE my_keyspace 
    WITH replication = {'class': 'NetworkTopologyStrategy', 'datacenter1': '2'}  
    AND durable_writes = true;

Now running queries on the cluster, the following issue occurs:

ReadFailure: Error from server: code=1300 [Replica(s) failed to execute read] 
message="Operation failed - received 0 responses and 1 failures" 
info={'consistency': 'LOCAL_ONE', 'received_responses': 0, 'required_responses': 1, 'failures': 1} 
info={'failures': None, 'consistency': 'Not Set', 'required_responses': None, 'received_responses': None}

Does anyone know what is causing this? If more information needed to better debug this problem, please let me know!


root# awk '!/#/' /etc/cassandra/conf/cassandra-rackdc.properties

  • Can you show content of the cassandra-rackdc.properties ? What query is executed? – Alex Ott Aug 22 '18 at 10:11
