Hi all, I am the administrator of a hadoop cluster. I want to know how to specify a group a user belong to. Or hadoop just use the group/user information from the linux system it runs on? For example, if a user 'smith' belongs to a group 'research' in the linux system. what is his account and group on HDFS?
Also, I want to know how to specify the prefix of the home directory. If there are two directories on HDFS, '/usr/smith' and 'user/smit'. When smith input 'bin/hadoop fs -ls ~/', which directory will he see? Thanks, -Gang
