Impossible d'importer les données d'Oracle à l'aide HDFS Sqoop

Question

Je suis en train d'importer des données de base de données Oracle XE à HDFS en utilisant la commande suivante:

sudo sqoop import -connect jdbc:oracle:thin:system/system@192.xxx.xx.x:1521:xe -username system -P -table employee -columns "ID" -target-dir sqoopoutput1 -m 1 

Cependant, il jette exception disant table non trouvé.

Please set $ACCUMULO_HOME to the root of your Accumulo installation.

La table existe dans la base de données XE (j'ai essayé le nom de la table sans les guillemets contrairement à la façon dont Sqoop tente d'interroger)

select * from employee 

S'il vous plaît aider.

Answer 1

Utilisez le nom de la table en majuscules.

sqoop import -connect jdbc:oracle:thin:system/system@192.xxx.xx.x:1521:xe -username system -P -table EMPLOYEE -columns "ID" -target-dir sqoopoutput1 -m
