RE: hive query fails

Could you give more details, it would be helpful if you could share the log files from the tasktracker for this job.
Your tracking url has details for the process, you could start from there and share the logs.

Dear all,

[hadoop@NHCLT-PC44-2 bin]$ hive
Logging initialized using configuration in file:/home/hadoop/Hive/conf/hive-log4j.properties
Hive history file=/home/hadoop/tmp/hadoop/hive_job_log_hadoop_201210011620_669979453.txt
hive> select count(1) from pokes;
Total MapReduce jobs = 1
Launching Job 1 out of 1
Number of reduce tasks determined at compile time: 1
In order to change the average load for a reducer (in bytes):
  set hive.exec.reducers.bytes.per.reducer=<number>
In order to limit the maximum number of reducers:
  set hive.exec.reducers.max=<number>
In order to set a constant number of reducers:
  set mapred.reduce.tasks=<number>
