Description

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.

EC Policy: rs-10-3-2048k
