Description

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.
