Zhijie Shen reopened YARN-947: ------------------------------ Need to add more history records > 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: Sub-task > Reporter: Zhijie Shen > Assignee: Zhijie Shen > Fix For: YARN-321 > > Attachments: YARN-947.1.patch, YARN-947.2.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.1#6144)
