--------------------------------
Summary: Defining the history data classes for the implementation
of the reading/writing interface
Key: YARN-947
URL: https://issues.apache.org/jira/browse/YARN-947
Project: Hadoop YARN
Issue Type: Bug
Reporter: Zhijie Shen
Assignee: Zhijie Shen
We need to define the history data classes have the exact fields to be stored.
Therefore, all the implementations don't need to have the duplicate logic to
exact the required information from RMApp, RMAppAttempt and RMContainer.
We use protobuf to define these classes, such that they can be ser/des to/from
bytes, which are easier for persistence.
