Fengdong Yu commented on HDFS-4983: ----------------------------------- [~yzhangal] : Thanks for fix, but I still have some comments here: a. please use USER_PATTERN_DEFAULT in all your test cases, insteadof hard code. b. WebHdfsConfigKeys.java {code} public static final String USER_PATTERN_DEFAULT = "^[A-Za-z_][A-Za-z0-9._-]*[$]?$"; {code} It should be {code} "^[A-Za-z0-9_][A-Za-z0-9._-]*[$]?$" {code} You passed all test cased because hard coded in all test cases, but it cannot succeed actually if you use USER_PATTERN_DEFAULT to test. > Numeric usernames do not work with WebHDFS FS > --------------------------------------------- > > Key: HDFS-4983 > URL: https://issues.apache.org/jira/browse/HDFS-4983 > Project: Hadoop HDFS > Issue Type: Improvement > Components: webhdfs > Affects Versions: 2.0.0-alpha > Reporter: Harsh J > Assignee: Yongjun Zhang > Labels: patch > Attachments: HDFS-4983.001.patch, HDFS-4983.002.patch, > HDFS-4983.003.patch > > > 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} -- This message was sent by Atlassian JIRA (v6.1#6144)
