Hadoop HDFS Java API to move files to hdfs

Question

I want to use a Java API to copy a file from one hdfs location (say hdfs://xyz:1234/sample-source/a.txt) to another hdfs location (say hdfs://xyz:1234/sample-destination/). I dont want to do it using hadoop/hdfs command and want to use Java API for it. Can someone tell me how I can implement this?

You can use the FileUtil api to do this. Example:

Configuration configuration = new Configuration();
configuration.set("fs.defaultFS", "hdfs://xyz:1234");
FileSystem filesystem = FileSystem.get(configuration);
FileUtil.copy(filesystem, new Path("src/path"), filesystem, new Path("dst/path"), false, configuration);
