hive hadoop: выбор данных из таблицы get error

Question

после того, как я создал внешнюю таблицу в Hive, я хотел знать количество твитов, поэтому я написал следующий запрос, но я получил эту ошибку, пожалуйста, как решить эту проблему, и это конфигурация mapred-site.xml

<configuration> 

<property> 
    <name>mapred.job.tracker</name> 
    <value>localhost:8021</value> 
    </property> 

hive> select count(*) from tweet;   
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_1464556774961_0005, Tracking URL = http://ubuntu:8088/proxy/application_1464556774961_0005/

Answer 1

Это связанно с отсутствующим модулем хранения улья-АФИ в улье-Exec банки. Вам нужно будет обновить куст до последней версии, чтобы вытащить последние исправления куста.

Временное исправление заключается в явном добавлении аппликатора хранения.

add jar ./dist/hive/lib/hive-storage-api-2.0.0-SNAPSHOT.jar;
