> Support random datanode ordering in getBlockLocations()
> -------------------------------------------------------
>
> Key: HDFS-17743
> URL: https://issues.apache.org/jira/browse/HDFS-17743
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: namenode
> Affects Versions: 2.10.0, 3.4.1
> Reporter: Wei Song
> Priority: Major
> Labels: pull-request-available
>
> At LinkedIn, we aren't able to rely on data locality due to various reasons,
> overall the current implementation of sorting by network topology didn't
> improve overall performance, it also caused unnecessary concentration of load
> on specific datanodes. We would like to request for a random policy that
> randomly order datanodes, we expect this policy to improve load distribution.
>
> The new policy should be configurable, and it is disabled. When enabled, it
> replaces the current network topology based datanode ordering.
