Example 1 with RSRawDecoder

use of org.apache.hadoop.io.erasurecode.rawcoder.RSRawDecoder in project hadoop by apache.

the class TestCodecRawCoderMapping method testRSDefaultRawCoder.

@Test
public void testRSDefaultRawCoder() {
    ErasureCoderOptions coderOptions = new ErasureCoderOptions(numDataUnit, numParityUnit);
    // should return default raw coder of rs codec
    RawErasureEncoder encoder = CodecUtil.createRawEncoder(conf, ErasureCodeConstants.RS_CODEC_NAME, coderOptions);
    Assert.assertTrue(encoder instanceof RSRawEncoder);
    RawErasureDecoder decoder = CodecUtil.createRawDecoder(conf, ErasureCodeConstants.RS_CODEC_NAME, coderOptions);
    Assert.assertTrue(decoder instanceof RSRawDecoder);
    // should return default raw coder of rs-legacy codec
    encoder = CodecUtil.createRawEncoder(conf, ErasureCodeConstants.RS_LEGACY_CODEC_NAME, coderOptions);
    Assert.assertTrue(encoder instanceof RSRawEncoderLegacy);
    decoder = CodecUtil.createRawDecoder(conf, ErasureCodeConstants.RS_LEGACY_CODEC_NAME, coderOptions);
    Assert.assertTrue(decoder instanceof RSRawDecoderLegacy);
