发现比较明显的错误是：

原因是这个目录在格式化的时候没有生成。
解决：
删除目录（之前我有安装过，后来删除重新安装才出现的这个问题）: /user/tmp
重新执行：bin/hdfs namenode -format格式化

提示格式化成功。
4、重新启动hdfs.
starting datanode, logging to /opt/modules/cdh/hadoop-2.5.-cdh5.3.6/logs/hadoop-walloce-datanode-bigdata-study-.out
[walloce@bigdata-study- hadoop-2.5.-cdh5.3.6]$ sbin/hadoop-daemon.sh start namenode

结束，重新搭建成功（小白初学中）!
