Review Comment:
> Because `sourceReader.addSplits(splits)` in the next line will log the
details of the splits, maybe we can simply have `LOG.info("Restoring state for
{} split(s) to reader.", splits.size())`?
yeah. i think u are right. because next SourceReaderBase will print adding
splits details.
