Google Cloud Bigtable Java客户端-技术错误 [英] Google Cloud Bigtable Java Client - tcnative errors

问题描述

我正在尝试连接到Cloud Bigtable；但是，我遇到了找不到netty-tcnative的问题.

I am trying to connect to Cloud Bigtable; however, I'm getting issues with netty-tcnative not being found.

Maven依赖项:

<dependency>
    <groupId>com.google.cloud.bigtable</groupId>
    <artifactId>bigtable-hbase-1.2</artifactId>
    <version>0.9.2</version>
</dependency>

<dependency>
    <groupId>io.netty</groupId>
    <artifactId>netty-tcnative-boringssl-static</artifactId>
    <version>1.1.33.Fork19</version>
</dependency>

推荐答案

此问题归因于Mule的类加载器. Mule在自己的类加载器中运行每个应用程序.需要将其移至Mule的通用类加载器(java.class.path)，而不是应用程序类加载器.确保BigTable客户端库和tcnative都在同一类路径中.

This issue was due to Mule's class loader. Mule runs each app in its own class loader. Need to move this to Mule's common class loader (java.class.path), rather than the app class loader. Ensuring both BigTable client library and tcnative is in the same classpath.

此问题将在其他容器(例如Tomcat)中出现，因为它们遵循类似的类加载器模式.

This issue would arise in other containers such as Tomcat, as they follow similar class loader patterns.
