Ok, the patch below actually works. Re-built Hadoop cluster and everything works now.
Now I have to understand how to force Hive to run >1 mapper for complicated query on the large table...

Subject: Hive and MapReduce


I'm running Hadoop 0.20.1 and Hive (checked out revision 824063).
Direct MapReduce task succeeds, but Map task created by Hive fails:

hive> select * from pokes where foo>100;
Total MapReduce jobs = 1
Number of reduce tasks is set to 0 since there's no reduce operator
Starting Job = job_200910111626_0001, Tracking URL = http://itstl0016.iil.intel.com:50030/jobdetails.jsp?jobid=job_200910111626_0001
Kill Command = /nfs/iil/disks/rep_tests_gtouret01/hadoop/bin/hadoop job -Dmapred.job.tracker=itstl0016.iil.intel.com:9001 -kill job_200910111626_0001
2009-10-11 04:26:57,844 map = 100%, reduce = 100%
Ended Job = job_200910111626_0001 with errors

Any suggestion?
I saw patches in https://issues.apache.org/jira/browse/HADOOP-5759?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12712524#action_12712524, but I can't apply all of them cleanly to my Hadoop sources...
