我有一个包含2个节点的火花群，master(172.17.0.229)和slave(172.17.0.228)。我已经修改了spark-env.sh，添加了SPARK_MASTER_IP=127.17.0.229和奴隶，添加了172.17.0.228。
我正在使用start-master.sh和从节点使用start-slaves.sh启动主节点。
我可以看到webUI的主节点没有worker，但是worker节点的日志是：

感谢您的建议。

通常，在172.17.0.229端口8080的Web UI上检查您的工作者尝试连接的IP与报告的SPARK_MASTER_IP=127.17.0.229
地址将有助于确定该地址是否正确。
在这种特殊情况下，看起来你有一个错字;变化
SPARK_MASTER_IP=172.17.0.229

@Override
public void onClick(View view) {
AlertDialog.Builder builder = new AlertDialog.Builder(view.getContext());
//do your stuff here.
}
（你似乎倒了127/172）。

我的问题是我使用的spark java库（2.0.0）和spark集群版本（2.2.1）之间的版本不匹配
