Alejandro Abdelnur commented on HDFS-4171: ------------------------------------------ Cross-posting with HDFS-4236: -------- Suresh, without HDFS-4171 usernames containing '_', '-' & '.' don't work. I think that is a bigger issue than the length limitation. I'd say it would be more common to have one of those chars in the username than a username with length greater than 31. Your opinion is against a config option. I'll take care of adding the release notes incompatible changes today or tomorrow. Sounds good? -------- > 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, HDFS-4171.patch, HDFS-4171.patch, > HDFS-4171.patch > > > HttpFs tries to use UserProfile.USER_PATTERN to match all usernames before a > doAs impersonation function.
