> Ozone: Add protobuf definitions for container reports
> -----------------------------------------------------

> Key: HDFS-11451
> URL: https://issues.apache.org/jira/browse/HDFS-11451
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: ozone
> Affects Versions: HDFS-7240
> Reporter: Anu Engineer
> Assignee: Anu Engineer
> Fix For: HDFS-7240
>
>
> Container reports are send from datanodes describing the state of the
> container. Since a full container report can be as large as 2 MB, the
> container reports are send by datanode only when SCM approves it.
> In this change, datanode informs the SCM that it has a container report
> ready. SCM based on load will send a command to datanode to send the actual
> report. The protobuf classes and plumbing required for that change is part of
> this patch. This whole container reports handling will be broken into
> multiple JIRAs to make it easy to code review.
