Arpit Agarwal commented on HDFS-5821:
-------------------------------------
Nice fix! Do the following expressions also need to be updated?
{code:xml}
<comparator>
<type>RegexpComparator</type>
<expected-output>^/user/[a-zA-z0-9]*/dir0/dir1</expected-output>
</comparator>
<comparator>
<type>RegexpComparator</type>
<expected-output>^/user/[a-zA-z0-9]*/dir0/dir2</expected-output>
</comparator>
{code}
> TestHDFSCLI fails for user names with the dash character

> testHDFSConf.xml uses regexes inconsistently to match the username from
> {code}[a-zA-z0-9]*{code} to {code}[a-z]*{code}. This by far does not cover
> the space of possible OS user names. For us, it fails for a user name
> containing {{'-'}}. Instead of keeping updating regex, we propose to use the
> macro USERNAME.
