max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
max number of threads [1024] for user [hadoop] is too low, increase to at least [2048]
max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
 

解决方案:

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

切换到root用户

 ulimit -Hn  查看硬限制

vim /etc/security/limits.conf 

添加下面设置 hadoop是用户

hadoop soft nofile 65536
hadoop hard nofile 65536

退出用户重新登录,使配置生效

重新 ulimit -Hn  查看硬限制 会发现数值有4096改成65535

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

找到如下内容:

soft nproc 1024

修改为

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
