> I was investigating test failure of TestIncrementalBackupWithBulkLoad from

> cfg.setLong(DistCpConstants.CONF_LABEL_TOTAL_NUMBER_OF_RECORDS,
> totalRecords);
> {code}
> For the test case, two bulk loaded hfiles are in the listing:

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