"Yanlış FS ... beklenen: file: ///" Java

Question

Java kullanarak HDF'ler bir dosyayı okumak için kuramıyorum içinde HDF'ler dosyayı okumaya çalışırken:

String hdfsUrl = "hdfs://<ip>:<port>"; 
Configuration configuration = new Configuration(); 
configuration.set("fs.defaultFS", hdfsUrl); 
FileSystem fs = FileSystem.get(configuration); 
Path filePath = new Path(hdfsUrl + "/projects/harmonizome/data/achilles/attribute_list_entries.txt.gz"); 
FSDataInputStream fsDataInputStream = fs.open(filePath); 

SEVERE: Servlet.service() for servlet [edu.mssm.pharm.maayanlab.Harmonizome.api.DownloadAPI] in context with path [/Harmonizome] threw exception 
java.lang.IllegalArgumentException: Wrong FS: hdfs://146.203.54.165:8020/projects/harmonizome/data/achilles/attribute_list_entries.txt.gz, expected: file:///

Ben kurulum vermedi HDFS'miz, ne bilmiyorum, bilmiyorum. Herhangi bir yardım takdir edilir.

bu deneyin:

Configuration configuration = new Configuration(); 
FileSystem fs = FileSystem.get(new URI(<url:port>), configuration); 
Path filePath = new Path(<path/to/file>); 
FSDataInputStream fsDataInputStream = fs.open(filePath); 
BufferedReader br = new BufferedReader(new InputStreamReader(fsDataInputStream));
