Error running terasort benchmark single node cluster

Hi,

I'm trying to run the Terasort benchmarks and i'm getting the following
exception:

The TeraGen commands run fine and have created the input files for
TeraSort. Here is the listing of my input directory:


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


Here is my command for running the terasort:


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


I do see the file _partition.lst in my input directory, i dont
understand why i am getting the FileNotFoundException. 

I followed the setup details provided at:
