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 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
