system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk

原因： 这是在因为Centos6不支持SecComp，而ES5.2.0默认bootstrap.system_call_filter为true进行检测，所以导致检测失败，失败后直接导致ES不能启动。

解决： 在elasticsearch.yml中配置bootstrap.system_call_filter为false，注意要在Memory下面:

bootstrap.memory_lock: false bootstrap.system_call_filter: false
