Hi Amit,
One way to accomplish this would be to create a custom writable
implementation, TextOrIntWritable, that has fields for both. It could look
something like:
class TextOrIntWritable implements Writable {
private boolean isText;
private Text text;
private IntWritable integer;
void writeFields(DataOutput out) {
out.writeBoolean(isText);
if (isText) {
text.writeFields(out);
} else {
integer.writeFields(out);
}
}
[... readFields method that works in a similar way]
}
