#############脚本使用说明####################################
#1、使用脚本前需要弄好服务器的基础环境#######################
#2、在hadoop的每个节点需要手动创建如下目录：/data/hdfs/tmp###
#3、修改下面的配置参数#######################################
#4、脚本执行完备后需要收到格式化namenode#####################
#5、格式化指令：hdfs namenode -format########################
#############################################################
#定义参数变量
#主节点域名

#从节点1域名,2NN的配置地址

#所有从节点信息
slaves=(slave-4 slave-5)
#java安装路径
