解决方案：elasticsearch

max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]oop

切换到root用户ip

ulimit -Hn 查看硬限制hadoop

vim /etc/security/limits.conf it

添加下面设置 hadoop是用户ast

hadoop soft nofile 65536
hadoop hard nofile 65536thread

退出用户从新登陆，使配置生效登录

从新 ulimit -Hn 查看硬限制会发现数值有4096改为65535配置

vim /etc/security/limits.d/90-nproc.conf

找到以下内容：

soft nproc 1024

修改成

soft nproc 2048

vi /etc/sysctl.conf

添加下面配置：

vm.max_map_count=655360

并执行命令：

sysctl -p
