Usage

From source file org.apache.cassandra.hadoop.AbstractColumnFamilyRecordWriter.java

/**
 * The <code>ColumnFamilyRecordWriter</code> maps the output &lt;key, value&gt;
 * pairs to a Cassandra column family. In particular, it applies all mutations
 * in the value, which it associates with the key, and in turn the responsible
 * endpoint.
 *
