Answer 1

You can use either of the two ways to solve your error.

1.

String infile = "file.txt";
Path ofile = new Path(infile);
FileSystem fs = ofile.getFileSystem(getConf());

2.

Configuration conf = getConf();
System.out.println("fs.default.name : - " + conf.get("fs.default.name"));
// It prints uri  as : hdfs://10.214.15.165:9000 or something
String uri = conf.get("fs.default.name");
FileSystem fs = FileSystem.get(uri,getConf());
