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?
