hadoop-2.7.0 启动hdfs出错？

Hi，各位hadoop大牛，我刚接触hadoop。所有的学习都是来源于网络。
昨天安装了hadoop，但是启动的时候hdfs报错。

查了下资料说是libhadoop.so.1.0.0, libhdfs.so.0.0.0是64位的。因为我Linux是32位的。要重新编译什么的，到底是不是真的呢？
若真是这样我根本不会编译额，请教。。。。。

把你的包，换成这个

再不行，就是配置问题了。
伪分布建议参考这个：

谢谢您的回答，我按照你给我发的安装帖子去重新对比了下几个xml文件的配置。
重新启动hadoop之后发现多了一个SecondaryNameNode。
[mw_shl_code=bash,true]
[hadoop@master sbin]$ jps
9461 Jps
8965 ResourceManager
8806 SecondaryNameNode
[/mw_shl_code]
但是启动的时候还是有Warning
[mw_shl_code=bash,true][hadoop@master ~]$ sh /home/hadoop/switch_hadoop.sh start

我的JDK是1.8.0，会有影响么？


补充内容 (2015-7-8 08:27):
查看了下，应该就是62位和32位的问题。

重新启动hadoop之后发现多 ...

最好使用jdk1.7,1.8目前还没有被普及。
缺进程，查看下日志。最有可能是权限出问题。

经过不同的尝试，在仍然有warn的情况下，我重新hadoop namenode -format。然后重启hadoop，最后成功！
[mw_shl_code=bash,true]
[hadoop@master ~]$ jps
16785 ResourceManager
16628 SecondaryNameNode

[hadoop@slave native]$ jps

1.虽然说是成功，能正常运行。但是在启动或者执行hadoop命令的时候都会有warn，但是不影响。
[mw_shl_code=bash,true]
[hadoop@master ~]$ hadoop dfs -ls /

Instead use the hdfs command for it.

2.还有一点我不是很明白，用file命令查看libhadoop.so.1.0.0显示的是64位（本机CentOS 32位）。这难道就是warn的原因？
[mw_shl_code=bash,true]
[hadoop@master ~]$ file ~/hadoop-2.7.0/lib/native/libhadoop.so.1.0.0
