Description

Unable to invoke 'hadoop jar' command for class, which contains Spring persistance unit.

The problem is that, the jar file uses Spring ORM for loading the persistance configurations, and based on these configurations,
i need to move the files to HDFS.

While invoking the jar with hadoop jar command (having spring orm injected) the exception is as:

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor#0' defined in class path resource [applicationContext.xml

Error creating bean with name 'entityManagerFactory' defined in class path resource [applicationContext.xml]:
Invocation of init method failed; nested exception is java.lang.IllegalStateException: Conflicting persistence unit definitions for name 'Persistance': file:/home/user/Desktop/ABC/apnJar.jar, file:/tmp/hadoop-user/hadoop-unjar2841422106164401019/
