在集群上安装 hadoop2.5.2

1.查看20台服务器环境。
发现没有hadoop用户，hosts已经更改。
2.下载hadoop2.5.2.查看zookeeper版本，发现是zookeeper 3.4.6，和线上不一致。
[root@hadoopNN1 ~]# cd /data/hadoop/data1/usr/local/setupSpark/
vim newslaves #把要部署的服务器列表放到此文件
scp houzhizhen@10.58.182.158:/usr/local/houzhizhen/zookeeper/zookeeper-3.4.6.tar.gz .
scp houzhizhen@10.58.182.158:/usr/local/hadoop/hadoop-2.5.2.tar.gz .
