В процессе изучения Sqoop я выполняю команду sqoop для извлечения всей базы данных mysql в DH Cloudera, которая корректно возвращает все доступные базы данных.Проблема заключается в том, что если я запускаю ту же команду, что и задание, в рабочем процессе Oozie, то всегда происходит сбой.
job.properties
nameNode=hdfs://quickstart.cloudera:8020
resourceManager=0.0.0.0:8032
oozie.use.system.libpath=true
oozie.wf.application.path=${nameNode}/user/${user.name}/oozie/pig_demo
