Я получаю следующую ошибку в Hive при выполнении любой команды.
hive> show tables;
FAILED: Error in metadata: javax.jdo.JDOFatalInternalException: Unexpected exception caught.
NestedThrowables:
java.lang.reflect.InvocationTargetException
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask
Это в hive.log.
