hadoop 安装 dfs 时发生 找不到本地库解决方式

在配置好hadoop 环境 并且配置好相关vml文件后 运行 start -dfs.sh 出现下面报错

Java HotSpot(TM) 64-Bit Server VM warning: You have loaded library /home/hadoop/hadoop-2.4.1/lib/native/libhadoop.so.1.0.0 which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c ', or link it with '-z noexecstack'.

18/01/29 17:14:23 WARN hdfs.DFSUtil: Namenode for null remains unresolved for ID null.  Check your hdfs-site.xml file to ensure namenodes are configured properly.

原因是hadoop 找不到本地库 网上说是因为 hadoop本地库与系统版本不一致引起 找到一下方式解决

 1. http://dl.bintray.com/sequenceiq/sequenceiq-bin/ 下载网址下找到hadoop对应版本的natice 文件下载后

2. 放到你的linux 系统里面后 解压到 hadoop安装目录下 /lib 

3. 重新运行dfs.sh 发现报错消失
