[jira] Moved: (HADOOP-6272) Incorrect UserName at Solaris because it has no "whoami" command by default

     [ https://issues.apache.org/jira/browse/HADOOP-6272?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Todd Lipcon moved HDFS-506 to HADOOP-6272:
------------------------------------------

          Component/s:     (was: documentation)
                       util
                       security
    Affects Version/s:     (was: 0.20.1)
                       0.21.0
                       0.20.1
                  Key: HADOOP-6272  (was: HDFS-506)
              Project: Hadoop Common  (was: Hadoop HDFS)

>             Project: Hadoop Common
>          Issue Type: Improvement
>          Components: security, util
>    Affects Versions: 0.20.1, 0.21.0
>         Environment: OS: SunOS 5.10
>            Reporter: Urko Benito
>         Attachments: PermissionChecker.java.diff, Shell.java.diff, test-hadoop-security.tar.gz, UnixUserGroupInformation.java.diff
>
>   Original Estimate: 24h
>  Remaining Estimate: 24h
>
> Solaris enviroment has no __whoami__ command, so the __getUnixUserName()__ at UnixUserGroupInformation class fails because it's calling to Shell.USER_NAME_COMMAND which is defines as "whoami".
> So it launched an Exception and set the default "DrWho" username ignoring all the FileSystem permissions.
