----------------------------------------
Some failed tests are shown below. We should make sure that all unit tests pass
if we run them individually. (It may be a boring job...)

Shall we declare the LOG as a static member ?
{noformat}
public class ChunkCreator {
private final Log LOG = LogFactory.getLog(ChunkCreator.class);

> For CellChunkMap we may need a cell such that the chunk out of which it was
> created, the id of the chunk be embedded in it so that when doing flattening
> we can use the chunk id as a meta data. More details will follow once the
> initial tasks are completed.
> Why we need to embed the chunkid in the Cell is described by [~anastas] in
> this remark over in parent issue
