Не удалось создать экземпляр org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient (Ubuntu)

Question

Я успешно установил Java, Hadoop MySQL. Я получаю эту ошибку во время работы с улей. Я получил ошибку разрешения файла, перед которой исправлено, установив папку metastore_db в папку hive в режим разрешений 777. Как я могу решить эту проблему.

Я пробовал даже перемещать файлы db.lck и dbex.lck. Это не сработало. Я перезапустил Hadoop и машину несколько раз после того, как изменения не сработали. Помогите ! Спасибо заранее.

Answer 1

Из свойства, она будет создавать только базу данных, но не схемы. Попробуйте создать схему, необходимую для метастара улья в MySQL.

cd $HIVE_HOME/scripts/metastore/upgrade/mysql/ 
< login to mysql > 
mysql> use metastore; 
mysql> source hive-schema-<your_version>.mysql.sql; 

Затем перезапустите процесс метаобработки куста.

Answer 2

Для меня я получил эту ошибку, когда не начинал улей внутри $ HIVE_HOME.
