How can I define a comparator that can compare raw binary data? (our keys
are raw binary data)
Implement the following method:
http://lucene.apache.org/hadoop/docs/api/org/apache/hadoop/io/WritableComparator.html#compare(byte[],%20int,%20int,%20byte[],%20int,%20int)
To make a comparator the default for a class, call:
http://lucene.apache.org/hadoop/docs/api/org/apache/hadoop/io/WritableComparator.html#define(java.lang.Class,%20org.apache.hadoop.io.WritableComparator)
This is already done for most WritableComparable implementations. The
the bottom of, e.g., IntWritable.java for an example of the idiom.
