title: Coordinator node timed out on Cassandra cqlsh shell
body: <p>I am new to cassandra and trying to do multi node setup on two Mac machine. Its not a datastax casandra.
  like my Ip is 10.100.1.12 and other machine ip is 10.100.1.15. I have changed the following properties in cassandra.yaml files on bothe the machine:</p>
  <p><strong><code>10.100.1.15:</code></strong></p>
  <ul>
  <li>seeds: &quot;127.0.0.1,10.100.1.12,10.100.1.15&quot;</li>
  <li>listen_address: 10.100.1.15</li>
  <li>rpc_address: 10.100.1.15</li>
  <li>endpoint_snitch: GossipingPropertyFileSnitch</li>
  </ul>
  <p><strong><code>10.100.1.12:</code></strong></p>
  <ul>
  <li><p>seeds: &quot;127.0.0.1,10.100.1.12,10.100.1.15&quot;</p>
  </li>
  <li><p>listen_address: 10.100.1.12</p>
  </li>
  <li><p>rpc_address: 10.100.1.12</p>
  </li>
  <li><p>endpoint_snitch: GossipingPropertyFileSnitch</p>
  <p>cassandra runs fine cqlsh is also opening using the command
  bin/cqlsh 10.100.1.12</p>
  </li>
  </ul>
  <p>but when i am trying to retrieve the count of tables its showing me the error:</p>
  <p><strong>ReadTimeout: Error from server: code=1200 [Coordinator node timed out waiting for replica nodes' responses] message=&quot;Operation timed out - received only 0 responses.&quot; info={'received_responses': 0, 'required_responses': 1, 'consistency': 'ONE'}</strong></p>
  <p>i tried changing the read_request_timeout_in_ms proprtty from 5000 to 20000 but still i am getting the same error. Could anyone please help what i am doing wrong?</p>
  <p>the table schema is following:</p>
  <pre><code>cqlsh:app_auditor&gt; describe table traffic_data;
  
  CREATE TABLE app_auditor.traffic_data (
      current_time bigint PRIMARY KEY,
      appid bigint,
      attributes map&lt;text, text&gt;,
      device bigint,
      flow_type text,
      message_time bigint
  ) WITH bloom_filter_fp_chance = 0.01
      AND caching = {'keys': 'ALL', 'rows_per_partition': 'NONE'}
      AND comment = ''
      AND compaction = {'class': 'org.apache.cassandra.db.compaction.SizeTieredCompactionStrategy', 'max_threshold': '32', 'min_threshold': '4'}
      AND compression = {'chunk_length_in_kb': '64', 'class': 'org.apache.cassandra.io.compress.LZ4Compressor'}
      AND crc_check_chance = 1.0
      AND dclocal_read_repair_chance = 0.1
      AND default_time_to_live = 0
      AND gc_grace_seconds = 86400
      AND max_index_interval = 2048
      AND memtable_flush_period_in_ms = 0
      AND min_index_interval = 128
      AND read_repair_chance = 0.0
      AND speculative_retry = '99PERCENTILE';
  </code></pre>
  <p>the count query i am using is
  select count(*) from traffic_data;</p>
