title: Not enough replica available for query at consistency ONE (1 required but only 0 alive)
body: <p>I have a Cassandra cluster with three nodes, two of which are up. They are all in the same DC. When my Java application goes to write to the cluster, I get an error in my application that seems to be caused by some problem with Cassandra:</p>
  
  <p>Caused by: com.datastax.driver.core.exceptions.UnavailableException: Not enough replica available for query at consistency ONE (1 required but only 0 alive)
      at com.datastax.driver.core.exceptions.UnavailableException.copy(UnavailableException.java:79)</p>
  
  <p>The part that doesn't make sense is that "1 required but only 0 alive" statement. There are two nodes up, which means that one should be "alive" for replication.</p>
  
  <p>Or am I misunderstanding the error message?</p>
  
  <p>Thanks.</p>
