Daryn Sharp commented on HDFS-12648:
------------------------------------
Yes, today commands are processed synchronously which stalls heartbeats. This
jira is under an umbrella that includes HDFS-12647 (async commands) which is
when/why this rate limiting is needed.
> DN should provide feedback to NN for throttling commands

> Key: HDFS-12648
> URL: https://issues.apache.org/jira/browse/HDFS-12648
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: datanode
> Affects Versions: 2.8.0
> Reporter: Daryn Sharp
> Assignee: Hanisha Koneru
>
> The NN should avoid sending commands to a DN with a high number of
> outstanding commands. The heartbeat could provide this feedback via perhaps
> a simple count of the commands or rate of processing.
