Alejandro Abdelnur moved HADOOP-9023 to HDFS-4171:
--------------------------------------------------
Key: HDFS-4171 (was: HADOOP-9023)
Project: Hadoop HDFS (was: Hadoop Common)
> HttpFs is too restrictive on usernames
> --------------------------------------
>
> Key: HDFS-4171
> URL: https://issues.apache.org/jira/browse/HDFS-4171
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Harsh J
>
> 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.
