> {code}
> private boolean invalidateBlock(BlockToMarkCorrupt b, DatanodeInfo dn
> ) throws IOException {
> ..
> } else if (nr.liveReplicas() >= 1) {
> // If we have at least one copy on a live node, then we can delete it.
> addToInvalidates(b.corrupted, dn);
> removeStoredBlock(b.stored, node);
> {code}
> We don't delete corrupted block if all we left is corrupted block. We give
> user the decision. So user has chance to recover it manually.
> We should not compare liveReplicas() of Striped block with "1". The logic
> need update.
