Let me know if you need something else.

> Key: HDFS-11391
> URL: https://issues.apache.org/jira/browse/HDFS-11391
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: webhdfs
> Affects Versions: 2.7.3
> Reporter: Pierre Villard
>
> In HDFS-4983, a property has been introduced to configure the pattern
> validating name of users interacting with WebHDFS because default pattern was
> excluding names starting with numbers.
> Problem is that this fix works only for read access. In case of write access
> against data node, the default pattern is still applied whatever the
> configuration is.
