----------------------------------------
Summary: Make IDs read only
Key: YARN-528
URL: https://issues.apache.org/jira/browse/YARN-528
Project: Hadoop YARN
Issue Type: Improvement
Reporter: Robert Joseph Evans
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.
