This can be fixed by modifying 
src/test/org/apache/hadoop/hdfs/BenchmarkThroughput.java:198

From:

198 String localDir = conf.get(mapred.temp.dir);
199 dir = new LocalDirAllocator(mapred.temp.dir);

To:

198 String localDir = conf.get(hadoop.tmp.dir);
199 dir = new LocalDirAllocator(hadoop.tmp.dir);

It looks as though this has been removed from subversion trunk though... but it 
still exists in 0.20.2/3, which I'm running currently.

Sorry, I should have noted that this assumes you have a hadoop.tmp.dir property 
configured in conf/core-site.xml. I was surprised that a Configuration object 
wasn't all-inclusive.
