> EC reconstruction failed with *java.lang.IllegalArgumentException: The chunk
> list has 9 entries, but the checksum chunks has 10 entries. They should be
> equal in size* exception. The DN had this problen when the EC data was
> reconstructed. And I found that this problem can occur whether the data block
> or the check block is missing.
