Hi everyone,
I am new to Hive. Here is a problem.

I followed the getting started instructions to setup my hive (as well as 
hadoop). I can create tables, show tables and select without any where clause. 
But once I do something that need to execute mapreduce jobs, it failed. A 
sample operation and the error is listed below:

hive> select a.id from age a where id=1;
Total MapReduce jobs = 1
Number of reduce tasks is set to 0 since there's no reduce operator
Starting Job = job_200910221333_0009, Tracking URL = 
http://localhost:50030/jobdetails.jsp?jobid=job_200910221333_0009
Kill Command = /home/lgpublic/bin/hadoop/hadoop-0.20.1/bin/.../bin/hadoop job  
-Dmapred.job.tracker=localhost:9001 -kill job_200910221333_0009
2009-10-22 04:19:50,787 map = 100%,  reduce = 100%
Ended Job = job_200910221333_0009 with errors
FAILED: Execution Error, return code 2 from 
org.apache.hadoop.hive.ql.exec.ExecDriver

I try the example in hive user guide (the u_data), it also failed. When I try 
to run a mapreduce jobs directly on hadoop, it works well. Could anyone give me 
some hints on this problem? Thanks.
