Hi Soheil,
That is a correct behavior. The full qualified path of you home directory in
HDFS is "{fs.defaultFS} + /user/myUserName" and getHomeDirectory complements it.
You can access paths by a few ways.
======
Configuration conf = new Configuration();
conf.set("fs.defaultFS","hdfs://nn-hostname");
FileSystem fs = FileSystem.get(conf);
// your home directory
fs.getFileStatus(new Path(".")) // relative path
fs.getFileStatus(new Path("/user/myUserName")) // absolute path
fs.getFileStatus(new Path("hdfs://nn-hostname/user/myUserName")) // full path
// root directory
fs.getFileStatus(new Path("/")) // absolute path
fs.getFileStatus(new Path("hdfs://nn-hostname/")) // full path
======
Thanks,

Subject: Wrong Root Directory in HDFS API
Hi,
I use HDFS java API to do some process. I pass HDFS configuration file
(core-site.xml and hdfs-site.xml) as Configuration. My Hadoop property
fs.defaultFS
has the value
hdfs://ha-cluster
but when I get HDFS home directory like the following:
FileSystem.get(conf).getHomeDirectory();
It has the value
hdfs://ha-cluster/user/myUserName
!!!
What is the reason and how can I set correct home directory?
