> Introduce redundancy.considerLoad.minLoad to avoiding excluding nodes when
> they are not busy actually
> -----------------------------------------------------------------------------------------------------
>
> Key: HDFS-17484
> URL: https://issues.apache.org/jira/browse/HDFS-17484
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: namenode
> Affects Versions: 3.4.0
> Reporter: farmmamba
> Assignee: farmmamba
> Priority: Minor
> Labels: pull-request-available
>
> Currently, we have `dfs.namenode.redundancy.considerLoad` equals true by
> default, and
> dfs.namenode.redundancy.considerLoad.factor equals 2.0 by default.
> Think about below situation. when we are doing stress test, we may deploy
> hdfs client onto the datanode. So, this hdfs client will prefer to write to
> its local datanode and increase this machine's load. Suppose we have 3
> datanodes, the load of them are as below: 5.0, 0.2, 0.3.
>
> The load equals to 5.0 will be excluded when choose datanodes for a block.
> But actually, it is not slow node when load equals to 5.0 for a machine with
> 80 cpu cores.
>
> So, we should better add a new configuration entry :
> `dfs.namenode.redundancy.considerLoad.minLoad` to indicate the mininum factor
> we will make considerLoad take effect.
