java.security.AccessControlExcep

在帮开发同事调试es远程词典的时候出现这个问题，elasticsearch 版本 6.2.3,jdk版本 1.8.0_102

解决办法：
vi /data/soft/jdk1.8.0_102/jre/lib/security/java.policy

// Standard extensions get all permissions by default

grant codeBase "file:${{java.ext.dirs}}/*" {
        permission java.security.AllPermission;
};

// default permissions granted to all domains

grant {
        // Allows any thread to stop itself using the java.lang.Thread.stop()
        // method that takes no argument.
        // Note that this permission is granted by default only to remain
        // backwards compatible.
        // It is strongly recommended that you either remove this permission
        // from this policy file or further restrict it to code sources
        // that you specify, because Thread.stop() is potentially unsafe.
        // See the API specification of java.lang.Thread.stop() for more
        // information.
        permission java.lang.RuntimePermission "stopThread";

        // allows anyone to listen on dynamic ports
        permission java.net.SocketPermission "localhost:0", "listen";

        // "standard" properies that can be read by anyone

        permission java.util.PropertyPermission "java.version", "read";
        permission java.util.PropertyPermission "java.vendor", "read";

        permission java.util.PropertyPermission "line.separator", "read";

        permission java.util.PropertyPermission "java.specification.version", "read";
        permission java.util.PropertyPermission "java.specification.vendor", "read";
        permission java.util.PropertyPermission "java.specification.name", "read";

        permission java.util.PropertyPermission "java.vm.specification.version", "read";
        permission java.util.PropertyPermission "java.vm.specification.vendor", "read";

        permission java.util.PropertyPermission "java.vm.version", "read";
        permission java.util.PropertyPermission "java.vm.vendor", "read";
        permission java.util.PropertyPermission "java.vm.name", "read";
        permission java.net.SocketPermission "*:*", "accept,connect,resolve"; //增加这一行内容
};

重启es之后解决
