Siddharth Seth updated YARN-528: -------------------------------- Attachment: y528_AppIdPart_03_fixUsage.txt y528_AppIdPart_02_AppIdChanges.txt y528_AppIdPart_01_Refactor.txt Uploading a bunch of patches to change ApplicationId to be immutable, without letting PB laek in. 01_Refactor - moves some of the common Record code into the API module. 02_ApplicationId is the actual ApplicationId change. 03_fixUsage - fixes places where the set api was being used. Chanhes ApplicationId creation to be via a static method in ApplicationId itself. Will upload another patch to run through jenkins. This is all WIP. > Make IDs read only > ------------------ > > Key: YARN-528 > URL: https://issues.apache.org/jira/browse/YARN-528 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Robert Joseph Evans > Assignee: Robert Joseph Evans > Attachments: y528_AppIdPart_01_Refactor.txt, > y528_AppIdPart_02_AppIdChanges.txt, y528_AppIdPart_03_fixUsage.txt, > y528_ApplicationIdComplete_WIP.txt, YARN-528.txt, YARN-528.txt > > > I really would like to rip out most if not all of the abstraction layer that > sits in-between Protocol Buffers, the RPC, and the actual user code. We have > no plans to support any other serialization type, and the abstraction layer > just, makes it more difficult to change protocols, makes changing them more > error prone, and slows down the objects themselves. > Completely doing that is a lot of work. This JIRA is a first step towards > that. It makes the various ID objects immutable. If this patch is wel > received I will try to go through other objects/classes of objects and update > them in a similar way. > This is probably the last time we will be able to make a change like this > before 2.0 stabilizes and YARN APIs will not be able to be changed. -- This message is automatically generated by JIRA.
