          Issue Type: Bug

When adding a DN to {{excludedNodes}}, it should log a warning message instead of info.
{code}
      success = createBlockOutputStream(nodes, storageTypes, 0L, false);

      if (!success) {
        LOG.info("Abandoning " + block);
        dfsClient.namenode.abandonBlock(block, stat.getFileId(), src,
            dfsClient.clientName);
        block = null;
        final DatanodeInfo badNode = nodes[errorState.getBadNodeIndex()];
        LOG.info("Excluding datanode " + badNode);
        excludedNodes.put(badNode, badNode);
      }
{code}
