From source file org.janusgraph.hadoop.formats.cassandra.CqlBridgeRecordReader.java

/**
 * <p> Background: The {@link org.apache.cassandra.hadoop.cql3.CqlRecordReader} class has changed
 * significantly in Cassandra-3 from Cassandra-2. This class acts as a bridge between
 * CqlRecordReader in Cassandra-2 to Cassandra-3. In essence, this class recreates CqlRecordReader
 * from Cassandra-3 without referring to it (because otherwise we'd get functionality from
 * CqlRecordReader on Cassandra-2 and we don't want it). </p>
