specify user name when connecting to hdfs

[Dong-iL, Kim]

Hi.
I’m trying to set external hdfs as state backend.
my os user name is ec2-user. hdfs user is hadoop.
there is a permission denied exception.
I wanna specify hdfs user name.
I set hadoop.job.ugi in core-site.xml and HADOOP_USER_NAME on command line.
but not works.
what shall I do?
thanks.
