QUESTION 1:    fatal: unable to access 'https://github.com/cloudera/Impala.git/': Failed to connect to github.com port 443: Timed out

DESCRIPTION: 在我clone/pull一个project时，出现这个问题！查询后发现因为自己配置了HTTP Proxy,而GIT的配置并没有更新相应的代理，导致不能正常访问。

SOLUTION: $ git config --global http.proxy http://{system_login_usr}:{system_login_pwd}@{proxy_address}:{proxy_port}

RESULT:      Cloning into 'Impala'...
fatal: unable to access 'https://github.com/cloudera/Impala.git/': error setting certificate verify locations:
CAfile: C:/Feng Guangyuan/Git/mingw64/ssl/certs/ca-bundle.crt
  CApath: none

QUESTION 2: 见问题1的结果

DESCRIPTION:ca-bundle.crt的定位错误，可能的原因为（1）windows下路径错误导致（2）windows下该文件的空白符/结束符导致

SOLUTION:（1）粗鲁式：$ git config --global http.sslverify false关闭认证

（2）

		Then add the config into ~/.gitconfig (if not existing, create it)
		**vim ~/.gitconfig**
		[http]
		    sslVerify = true
		    sslCAinfo = /etc/ca-certificates/extracted/ca-bundle.trust.cr

RESULT:

Cloning into 'Impala'...
