Christian Tzolov updated CRUNCH-491:
------------------------------------
Attachment: CRUNCH-491f.patch
Apparently the assumption that one can't re-compute the original (raw) byte
size for a given characters is not correct. Following [~champgm] suggestion to
use CharsetEncoder seems to do the trick.
{code}
public static class XmlRecordReader extends RecordReader<LongWritable, Text> {
...
private int calculateCharacterByteLength(final char character) {
try {
return charsetEncoder.encode(CharBuffer.wrap(new char[] { character
})).limit();
} catch (final CharacterCodingException e) {
throw new RuntimeException(inputEncoding);
}
}
}
{code}

> broken into chunks delimited by the start and end tags of those elements.
> The XmlSource should process XML files and extract out the XML between the
