Write image (byte array) to hdfs

Question

I have a pig UDF function written in java which is creating a chart and I need to save the chart to HDFS.

Code from java UDF:

byte[] bytes = BitmapEncoder.getBitmapBytes(chart, BitmapFormat.PNG);

How can I save the image (byte array) to HDFS ?

Answer 1

Solved it:

byte[] bytes = BitmapEncoder.getBitmapBytes(chart, BitmapFormat.PNG);

    Configuration config = new Configuration();
    FileSystem fs = FileSystem.get(config);
    String s = fs.getHomeDirectory()+"/chart.png";
    Path path = new Path(s);
    FSDataOutputStream out = fs.create(path);
    out.write(bytes);
    out.close();
