示例1: open

import org.apache.hadoop.io.compress.CompressionCodecFactory; //导入方法依赖的package包/类
@Override
public void open(FileSystem fs, Path path) throws IOException {
	super.open(fs, path);
	if (keyClass == null) {
		throw new IllegalStateException("Key Class has not been initialized.");
	}
	if (valueClass == null) {
		throw new IllegalStateException("Value Class has not been initialized.");
	}

	CompressionCodec codec = null;

	Configuration conf = fs.getConf();

	if (!compressionCodecName.equals("None")) {
		CompressionCodecFactory codecFactory = new CompressionCodecFactory(conf);
		codec = codecFactory.getCodecByName(compressionCodecName);
		if (codec == null) {
			throw new RuntimeException("Codec " + compressionCodecName + " not found.");
		}
	}

	// the non-deprecated constructor syntax is only available in recent hadoop versions...
	writer = SequenceFile.createWriter(conf,
			getStream(),
			keyClass,
			valueClass,
			compressionType,
			codec);
