Hive CLI启动报错Impossible d'instancier org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient

Arrière-plan

Lors du démarrage du client Hive sur le cluster Hadoop, l'erreur suivante est signalée :

ÉCHEC : SemanticException org.apache.hadoop.hive.ql.metadata.HiveException : java.lang.RuntimeException : impossible d'instancier org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient

Généralement, cela est dû au fait que le service metastore n'est pas activé.

Solution

1. Avant : HIVE_HOME a été ajouté en tant que variable d'environnement système
2. saisir la commande
   hive --service metastore &

➜  ext source ~/.zshrc                                                                                                
➜  ext hive --service metastore &

Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.

3. Entrez à nouveau la commande Hive pour accéder à l'interface de ligne de commande interactive Hive :

➜  lib hive
