Hi, this follows the following feature in this feature [1]
I'm trying to implement a custom persistence engine and a leader agent in the Java environment. vis-a-vis scala, when I implement the PersistenceEngine trait in java, I would have to implement methods such as readPersistedData, removeDriver, etc together with read, persist and unpersist methods. but the issue here is, methods such as readPersistedData etc are 'final def's, hence can not be overridden in the java environment. I am new to scala, but is there any workaround to implement the above traits in java? look forward to hear from you. [1] https://issues.apache.org/jira/browse/SPARK-1830 -- Niranda
