> In case if timestamps for KeyValues specified differently for different
> column families, then TIMERANGEs of both HFiles would be wrong.
> Example (in pseudo code): my reducer has a condition
> if ( condition ) {
> keyValue = new KeyValue(.., CF1, .., timestamp, ..);
> } else {
> keyValue = new KeyValue(.., CF2, .., ..); // <- no timestamp
> }
> context.write( keyValue );
> These two keyValues would be written into two different HFiles.
> But the code, which is actually write do the following:
> // we now have the proper HLog writer. full steam ahead
> kv.updateLatestStamp(this.now);
> trt.includeTimestamp(kv);
> wl.writer.append(kv);
> Basically, two HFiles shares the same instance of trt (TimeRangeTracker),
> which leads to the same TIMERANGEs of both of them. Which is definitely
> incorrect, because first HFile must have TIMERANGE=timestamp...timestamp,
> cause we do not write any other timestamps there. And another HFile must have
> TIMERANGE=now...now by same meaning.
