Urko Benito commented on HDFS-506:
----------------------------------
Hi
I think the solution is *not to change the source code* but, keep in mind that
*this is not the correct way* (but until HADOOP-4487 is solved) i proposed a
solution
* Update the _prerequisites_ at wiki page saying something like *keep in mind
whoami, bash and md5sum must be present and accesible to hadoop process*
* Add some _Hadoop Solaris Installation Guide_ to the official doc
I'm writing a _Installing Hadoop on Solaris Guide_ at my blog, but at the
moment is in Spanish, i'll translated it to English and add to the issue.
What do you think about?
> Incorrect UserName at Solaris because it has no "whoami" command by default

> Key: HDFS-506
> URL: https://issues.apache.org/jira/browse/HDFS-506
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: build
> Affects Versions: 0.20.1
> 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.
