Я создал таблицу улья, как в Создание внешнего с разделом
Я использую версию куста hive-0.7.1-cdh3u2.Когда я запустил простой запрос, т. Е. Выберите count (*), я получаю сообщение об ошибке.
hive> select count(*) from test where dt='2012-01-30' and hr='17';
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>
Starting Job = job_201201311809_0006, Tracking URL = http://localhost:15030/jobdetails.jsp?jobid=job_201201311809_0006

Ended Job = job_201201311809_0006 with errors
И ошибка Jobtracker:
