When I run the code
String s = in.readLine();
System.out.println("readline -------- "+s+"\n");
flatJson = JSONFlattener.parseJson(s);
if (hdfs.exists(new Path(hdfsUri + dirName + "/" + filename))) {
outStream = hdfs.append(new Path(hdfsUri + dirName + "/" + filename));
BufferedWriter br = new BufferedWriter(new OutputStreamWriter(outStream));
br.append(CSVWriter.getCSV(flatJson));
br.close();
} else {
outStream = hdfs.create(new Path(hdfsUri + dirName + "/" + filename));
IOUtils.write((CharSequence) CSVWriter.getCSV(flatJson), outStream);
}
I get

What is that exception missing storage id. I have two node cluster and both of them has hadoop-2.8.0. Why is that error then my hadoop setup
hdfs = FileSystem.get(URI.create(hdfsUri), con);
hdfs.mkdirs(new Path(hdfsUri + "/" + dirName));
hdfs.setReplication(new Path(hdfsUri + "/" + dirName + "/" + filename), (short) 1);
I am fetching data from a url and writing to hdfs and I am fetching on daily basis and since perday data is small I thought it would be good to make single large file by appending rather than writing to small individual files.But appending is not working.I have set replication factor to 1.
