Settings settings = Settings.builder().put("cluster.name", "xxx")

                    .put("xpack.security.transport.ssl.enabled", false)

                    .put("xpack.security.user", "xxx:xxx")

                    .put("client.transport.sniff", true).build();

try {

    client = new PreBuiltXPackTransportClient(settings)

            .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("xxx.xxx.xxx.xxx"), 9300))

            .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("xxx.xxx.xxx.xxx"), 9300));

} catch (UnknownHostException e) {

    e.printStackTrace();

java.lang.IllegalArgumentException: unknown setting [xpack.security.transport.ssl.enabled] please check that any required plugins are installed, or check the breaking changes documentation for removed settings

我的是5.0.1，安装了x-pack，采用楼主相同的写法，但是报错，求指导

novia

你访问集群需要密码吗？

huhansan 回复 novia

需要密码

huhansan

PreBuiltXPackTransportClient这个来源于哪个jar包，我下了transport包但是没有该类

请问像这种情况是什么问题

自己蠢了。。。。
已解决，"xpack.security.user","xx:xx"参数理解错误

caster_QL

xpack安全模块 user roles管理有java的 API嘛

duchao 回复 huhansan

你后面解决了吗，我也没找到

duchao 回复 W861642669

楼主能帮我解答一下这个问题的原因吗？

happytjn 回复 gd839910312

提示里已经表明出错原因里，availableProcessors is already set to [8], rejecting [8] at at io.netty.util.NettyRuntime$AvailableProcessorsHolder.setAvailableProcessors(NettyRuntime.java:51)
说明 NettyRuntime的setAvailableProcessors被调用了二次，第二次被拒绝了

继续看下一条出错提示: at org.elasticsearch.transport.netty4.Netty4Utils.setAvailableProcessors(Netty4Utils.java:87)
貌似在Netty4Utils里源码里你会看到，有个“es.set.netty.runtime.available.processors”配置，当设置为false时，就不会再调用setAvailableProcessors方法了
