HDFS Login Security

Hi,
     Do we have any Java class for Login purpose to HDFS programmatically like traditional UserName/Password mechanism ? or we can have only system user or user who started NameNode ?

Thanks,

Wasim

It's not a complete security system, though. There's no authentication -- it
trusts the username you enter. I think Kerberos auth is coming, but not
ready yet

Look at the "hadoop.job.ugi" configuration option.  You can manually set a
user and the groups that user is a part of.
