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

};
重启es之后解决
