Examples of BytesRefWritable

org.apache.hadoop.hive.serde2.columnar.BytesRefWritable
BytesRefWritable referenced a section of byte array. It can be used to avoid unnecessary byte copy.

Examples of org.apache.hadoop.hive.serde2.columnar.BytesRefWritable

    cloneConf.setInt(RCFile.RECORD_INTERVAL_CONF_STR, intervalRecordCount);
    RCFile.Writer writer = new RCFile.Writer(fs, cloneConf, testFile, null, codec);    


    BytesRefArrayWritable bytes = new BytesRefArrayWritable(bytesArray.length);
    for (int i = 0; i < bytesArray.length; i++) {
      BytesRefWritable cu = null;
      cu = new BytesRefWritable(bytesArray[i], 0, bytesArray[i].length);
      bytes.set(i, cu);
    }
    for (int i = 0; i < writeCount; i++) {
      writer.append(bytes);
