Subject [jira] [Commented] (HDFS-11492) Ozone: Add the ability to handle sendContainerReport Command

Yuanbo Liu commented on HDFS-11492:
-----------------------------------

[~anu] Thanks for filing this JIRA. Not sure whether you're working on it. I'd like to share
my questions about this JIRA:
* Do you want to handle SCM commands in a new thread, or after heartbeat finished? I see you
store commands into {{StateContext#commandQueue}} and assume you want to do it in another
thread.
* Do you have any pattern design about this part? It's important to handle commands in DataNode.

> Once a container report is ready datanodes sends that information to SCM. SCM returns
a command asking the data node to send container report. Add the ability to handle this command
on datanode side and send the actual container Report.
