我正在尝试运行Terasort基准测试,我得到以下异常：

TeraGen命令运行正常,并为TeraSort创建了输入文件.这是我的输入目录的列表：
bin/hadoop fs -ls /user/hadoop/terasort-input/Warning: Maximum heap size rounded up to 1024 MB Found 5 items -rw-r--r-- 1 sqatest supergroup 0 2012-01-23 14:13 /user/hadoop/terasort-input/_SUCCESS drwxr-xr-x - sqatest supergroup 0 2012-01-23 13:30 /user/hadoop/terasort-input/_logs -rw-r--r-- 1 sqatest supergroup 129 2012-01-23 15:49 /user/hadoop/terasort-input/_partition.lst -rw-r--r-- 1 sqatest supergroup 50000000000 2012-01-23 13:30 /user/hadoop/terasort-input/part-00000 -rw-r--r-- 1 sqatest supergroup 50000000000 2012-01-23 13:30 /user/hadoop/terasort-input/part-00001
这是我运行terasort的命令：
bin/hadoop jar hadoop-examples-0.20.203.0.jar terasort -libjars hadoop-examples-0.20.203.0.jar /user/hadoop/terasort-input /user/hadoop/terasort-output
我在输入目录中看到文件_partition.lst,我不明白为什么我得到FileNotFoundException.
我按照http://www.michael-noll.com/blog/2011/04/09/benchmarking-and-stress-testing-an-hadoop-cluster-with-terasort-testdfsio-nnbench-mrbench/提供的设置详细信息进行操作
