line delimiter is control by RecorderWriter, see TextRecordWriter as an
example:
``` scala
public void write(Writable row) throws IOException {
Text text = (Text) row;
Text escapeText = text;
if (HiveConf.getBoolVar(conf, HiveConf.ConfVars.HIVESCRIPTESCAPE)) {
escapeText = HiveUtils.escapeText(text);
}
out.write(escapeText.getBytes(), 0, escapeText.getLength());
out.write(Utilities.newLineCode);
}
```
