-------------------------------------

Patch looks good. 
I  agree that fixing the {{testPlanReadPortions}} to suite default schema would 
be tricky. Anyway it has to support multiple codecs of different sizes. Let 3 
one of those.

One nit.
remote unused import in {{TestReadStripedFile}}

+1 after that

> It's not easy to remove the hard-coded values to use the system default 
> schema. We may need several steps/issues to cover relevant aspects. First of 
> all, let's make the hard-coded values consistent with the system default 
> schema first. This might not so easy, as experimental test indicated, when 
> change the following two lines, some tests then failed.
> {code}
> -  public static final byte NUM_DATA_BLOCKS = 3;
> -  public static final byte NUM_PARITY_BLOCKS = 2;
> +  public static final byte NUM_DATA_BLOCKS = 6;
> +  public static final byte NUM_PARITY_BLOCKS = 3;
> {code}
