It looks like the mapper crashed athe end. Can you click on the tracking url and click on the mapper link and post the log file?
As Namit said it may be a wrong version.

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.
