在Centos7上启动Hadoop的HDFS时遇到两个错误：1. 由于未设置环境变量导致的启动问题，解决方案是在~/.bash_profile或/etc/profile中添加相关配置。2. SSH的Host key verification failed错误，可通过修改/etc/ssh/ssh_config文件，调整StrictHostKeyChecking参数来解决。

It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.
