Description

Following errors were found intermittently due to which Atlas server won’t start up. These errors pointed to a circular dependency issue which was caused by TaskRegistry class(repository/src/main/java/org/apache/atlas/tasks/TaskRegistry.java) As a resolution to this, @Lazy annotation is added on @Component definition of this class.
(FYI : A @Lazy bean is not initialised until referenced by another bean or explicitly retrieved from BeanFactory . Beans that are not annotated with @Lazy are initialise eagerly.)

 

org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'taskRegistry': Bean with name 'taskRegistry' has been injected into other beans [taskManagement] in its raw version as part of a circular reference, but has eventually been wrapped. This means that said other beans do not use the final version of the bean. This is often the result of over-eager type matching - consider using 'getBeanNamesForType' with the 'allowEagerInit' flag turned off, for example.
