Description

  
  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);

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.
