RandomWriter writes random data sequentially, not data at random (i.e. non-sequential) locations. See http://wiki.apache.org/lucene-hadoop/RandomWriter. It's useful for generating data for sort benchmarking (http://wiki.apache.org/lucene-hadoop/Sort).

Well, I found an example in the hadoop's source package: hadoop/src/examples/org/apache/hadoop/examples/ A java file named RandomWriter.java, it seemed that the hadoop does support random writes. I'm not sure,what's your opinion?
