Work Description: ZanderXu opened a new pull request, #4441:
URL: https://github.com/apache/hadoop/pull/4441
This PR is about RBF IPC changes in order to support Observer-Read.
And this a draft PR, and relevant
[PR](https://github.com/apache/hadoop/pull/4311) already exist.
Different point:
- Proxy always with AlignmentContext, like RouterGSIContext which contains a
boolean flag, like enableObserverRead
- Always update the lastSeenStateId from active
- If enableObserverRead is false, updateRequestState will not set
lastSeenStateId in RPCHeader
- It's easily to dynamically reconfigure enableObserverRead.
