Installing Kafka on Mac OS X

Homebrew is a great little package manager for OS X. If you haven't already, installing it is pretty easy:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

	#!/bin/bash
	# kinit helper - 解决单用户并发 kinit 报错问题
	# 只有当 expiredTime 剩余时间小于 2 小时才进行 kinit 操作，且只允许一次 kinit
	source /etc/profile

	# 输入参数 $1=租户 $2=租户密码
	proxyUser=$1
	passwd=$2
	# 是否需要 kinit (默认需要=0)
	needKinit=0
