Kai Zheng commented on HDFS-8104:
---------------------------------

Looks like it's not quite much for this after some investigation. I will handle 
HDFS-8105 here together as suggested by [~jingzhao]. Thanks.

> 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}
