Description

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.
