> Currently, when we execute countNodes method for a striped block, if a
> datanode has two ec blocks with different block id (because of some special
> cases and I will find and fix it laterly.). One block is LIVE, the other is
> CORRUPT. Current logic will compute two CORRUPT replicas because
> corruptReplicas contains the datanode. We should fix it.
