> The above warning shouldn't happen - the two bulk loaded hfiles are

> From the contents of the two CopyListingFileStatus instances, we can see that

> if (isSplit()) {

> sb.append(", chunkLength = ").append(this.getChunkLength());
> }
> {code}
> From hbase side, we can specify one bulk loaded hfile per job but that
> defeats the purpose of using DistCp.
