> Coalesce IBR processing in the NN

> Key: HDFS-9198
> URL: https://issues.apache.org/jira/browse/HDFS-9198
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: namenode
> Affects Versions: 2.0.0-alpha
> Reporter: Daryn Sharp
> Assignee: Daryn Sharp
> Attachments: HDFS-9198-branch2.patch, HDFS-9198-trunk.patch,

>
>
> IBRs from thousands of DNs under load will degrade NN performance due to
> excessive write-lock contention from multiple IPC handler threads. The IBR
> processing is quick, so the lock contention may be reduced by coalescing
> multiple IBRs into a single write-lock transaction. The handlers will also
> be freed up faster for other operations.
