-------------------------------------

Hi, All.

I want to use hbase.mapred on shell.
But, when I try to submit a job to the JobTracker, I get this exception error message.

{code}
2007-07-14 20:37:04,377 INFO org.apache.hadoop.mapred.TaskInProgress: 
Error from task_200707142013_0004_r_000000_2: 
java.lang.RuntimeException: java.lang.RuntimeException: 
java.lang.ClassNotFoundException: 
org.apache.hadoop.hbase.mapred.IdentityTableReduce
{code}

How can i fix it without another changes ?
Please give me some advice.
