Subject Terasort benchmarks (Error in configuring object)
Date Fri, 10 Feb 2012 03:36:14 GMT

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

-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:
