    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
