> Add journalnode maintenance node list
> -------------------------------------

> Key: HDFS-17223
> URL: https://issues.apache.org/jira/browse/HDFS-17223
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: qjm
> Affects Versions: 3.3.6
> Reporter: kuper
> Priority: Major
> Labels: pull-request-available
>
> * In the case of configuring 3 journal nodes in HDFS, if only 2 journal nodes
> are available and 1 journal node fails to start due to machine issues, it
> will result in a long initialization time for the namenode (around 30-40
> minutes, depending on the IPC timeout and retry policy configuration).
> * The failed journal node cannot recover immediately, but HDFS can still
> function in this situation. In our production environment, we encountered
> this issue and had to reduce the IPC timeout and adjust the retry policy to
> accelerate the namenode initialization and provide services.
> * I'm wondering if it would be possible to have a journal node maintenance
> list to speed up the namenode initialization knowing that one journal node
> cannot provide services in advance?
