在使用grpc过程中偶尔会遇到下面报错：

出现上面的错误，分别有以下几种情况第一种：grpc服务地址没有配置，这种情况要么是搞忘记配置，或者没有加载配置，也可能是是配置信息存储在配置中心，且服务中发布到docker容器中且继承了istio，这种是域名相关配置istio还没初始化，从而导致拉取配置失败第二种：netty-tcnative相关的maven库没引入根据grpc对应的版本，有以下对应关系

详情可以查看下面连接https://github.com/grpc/grpc-java/blob/master/SECURITY.md 由于我用的netty-grpc是1.15.1，所以这里配置是2.0.12.Final，如下

<dependency>
    <groupid>io.netty</groupid>
    <artifactid>netty-tcnative</artifactid>
    <version>2.0.12.Final</version>
</dependency>

第三种：如果是发布在容器中，需要更换jdk基础镜像 openjdk:8-jdk-alpine 修改为 openjdk:8 https://gitmemory.com/issue/grpc/grpc-java/5369/493463266
