Kihwal Lee commented on HDFS-4171: ---------------------------------- I see a lot of webhdfs test failures ever since this was committed. Looking at the precommit build which +1'ed for everything, it actually failed. > WebHDFS and HttpFs should accept only valid Unix user names > ----------------------------------------------------------- > > Key: HDFS-4171 > URL: https://issues.apache.org/jira/browse/HDFS-4171 > Project: Hadoop HDFS > Issue Type: Bug > Affects Versions: 2.0.2-alpha > Reporter: Harsh J > Assignee: Alejandro Abdelnur > Fix For: 2.0.3-alpha > > Attachments: HDFS-4171.patch > > > HttpFs tries to use UserProfile.USER_PATTERN to match all usernames before a > doAs impersonation function. This regex is too strict for most usernames, as > it disallows any special character at all. We should relax it more or ditch > needing to match things there. > WebHDFS currently has no such limitations. -- This message is automatically generated by JIRA.
