集群同步hive的脚本

程序员就是把一切手工做的事情变成让计算机来做，从而可以让自己偷偷懒。

以下就是个非常low的hive文件夹同步程序，至于节点超过100个或者1000个的，可以加个循环了。

#!/bin/sh

#================ hive 安装包同步 =================#
# 该脚本用来将name节点的hive文件夹同步到data节点   #
# 当hive安装包变动时，需要同步data节点，否则oozie  #
# 通过shell调用hive程序时，会因为分配的节点hive安  #
# 装包不同步而引起错误                             #
#==================================================#

# .清理旧的hive
ssh -t hadoop@dwprod-dataslave1 rm -r /opt/local/hive
ssh -t hadoop@dwprod-dataslave2 rm -r /opt/local/hive
ssh -t hadoop@dwprod-dataslave3 rm -r /opt/local/hive

ssh -t hadoop@dwprod-dataslave9 rm -r /opt/local/hive
ssh -t hadoop@dwprod-dataslave10 rm -r /opt/local/hive
