最近在使用ES在做数据库，之前一直在本地测试，所以ES配置文件中的一直都是用的
network.host: 192.x.x.x，然后把项目放到测试环境以后，就把该条配置注释了，发现注释以后项目连接有问题，于是就把该配置放开，再启动ES，然后就巴拉巴拉打印了一堆错误，具体错误如下：

Exception in thread "main" SettingsException[Failed to load settings from */elasticsearch.yml]; nested: MarkedYAMLException[while parsing a block mapping
 in 'reader', line 17, column 1:
    cluster.name: beehive
    ^
expected <block end>, but found BlockMappingStart
 in 'reader', line 55, column 2:
     network.host: 192.X.X
     ^

从错误第一行可以看出，读取配置文件错误，但是，不应该啊，我就是把注释去掉而已，怎么就出问题了呢？？？？？
仔细看了配置文件发现原来 network.host: 192.x.x.x这个配置没有定格写，前面有一个空格，what，这样不能解析？
查了一下，好像还真是不能有空格，只能说一句，小老弟，你这是看我眼神好咋滴。
对了，我使用的ES版本是elasticsearch-5.5.2，不知道其他的版本有没有这个问题，希望添加校验吧，要不然太容易出错了。
