Time taken: 7.366 seconds

 

But when the sql is ‘select id from table1;’, hive throws a exception:

 

2011-03-22 14:12:46,612 Stage-1 map = 0%,  reduce = 0%

2011-03-22 14:13:13,984 Stage-1 map = 100%,  reduce = 100%

Ended Job = job_201103221411_0001 with errors

 

FAILED: Execution Error, return code 2 from
org.apache.hadoop.hive.ql.exec.ExecDriver

 

Here is the hadoop log:
