        Collect all the chunk metadata of current series from the source files.

        If there are any modifications for these chunk, we will apply them to the metadata. Use `ChunkMetadata.getDeleteIntervalList() == null` to judge if the chunk is modified.

        Returns:
        Throws:
        org.apache.iotdb.commons.exception.IllegalPathException
