Harsh J commented on HDFS-4983:
-------------------------------
bq. For example, what does it mean if I making this configuration empty?
It means you are configuring the said property incorrectly? Same argument can
be used for a whole lot of different configurations we offer (all of which have
saved ops at one time or another when a need has arose). I don't see your
point, sorry.
bq. I think that this change does bring in some configuration burdens.
We have a default that is flexible via configuration. Its not a mandatory
configuration.
bq. let's focus on supporting numeric usernames in this jira and move forward.
If you're interested in making this configurable, let's open a separate jira
for it.
I disagree but as you wish. I simply do not want a difference between WebHDFS
and HTTPFS, which is what I filed this ticket for. If you see removal of any
form of username restriction as a valid step for this, then lets also remove it
from HTTPFS at the same time.

> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: webhdfs
> Affects Versions: 2.0.0-alpha
> Reporter: Harsh J
> Assignee: Yongjun Zhang

> Per the file
> hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/web/resources/UserParam.java,
> the DOMAIN pattern is set to: {{^[A-Za-z_][A-Za-z0-9._-]*[$]?$}}.
> Given this, using a username such as "123" seems to fail for some reason
> (tried on insecure setup):
> {code}
> [123@host-1 ~]$ whoami
> 123
> [123@host-1 ~]$ hadoop fs -fs webhdfs://host-2.domain.com -ls /
> -ls: Invalid value: "123" does not belong to the domain
> ^[A-Za-z_][A-Za-z0-9._-]*[$]?$
> Usage: hadoop fs [generic options] -ls [-d] [-h] [-R] [<path> ...]
> {code}
