Subject [jira] Commented: (HDFS-506) Incorrect UserName at Solaris because it has no "whoami" command by default
Date Tue, 28 Jul 2009 18:05:15 GMT

    [ https://issues.apache.org/jira/browse/HDFS-506?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12736186#action_12736186
] 

Tsz Wo (Nicholas), SZE commented on HDFS-506:
---------------------------------------------

BTW, Hudson is using Solaris (see http://hudson.zones.apache.org/hudson/job/Hadoop-Patch/).
 So I guess the whoami command exists in Solaris.

> 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.
