> Allows client to actively retry to Active NameNode when the Observer NameNode

> Key: HDFS-17769
> URL: https://issues.apache.org/jira/browse/HDFS-17769
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: namenode
> Affects Versions: 3.3.4, 3.3.6, 3.4.1
> Reporter: Guo Wei
> Priority: Major
> Labels: pull-request-available
> Fix For: 3.4.2
>
> Attachments: 1.png, 2.png, 3.png
>
>
> When we use Router to forward read requests to the observer, if the cluster
> experiences heavy write workloads, Observer nodes may fail to keep pace with
> edit log synchronization, even if the dfs.ha.tail-edits.in-progress parameter
> is configured, it may still occur.
> This triggers RetriableException: Observer Node is too far behind errors.
> Especially when the client ipc.client.ping parameter is set to true, it will
> strive to wait and constantly retry, which can cause the business to be
> unable to obtain the desired data timely. We should consider having the
> active namenode handle this at this time.
> Here are our some errors and repair verification：
> The stateid of the observer is too far behind the active：1.png
>
> RetriableException：2.png

> repair verification : 3.png
