谷歌 BigTable 访问错误

Question

我需要在我的 java 应用程序中读取 BigTable。我正在使用 google-cloud-bigtable hbase 客户端。我已将依赖项添加到我的 pom 文件中：

<dependency>
   <groupId>com.google.cloud.bigtable</groupId>
   <artifactId>bigtable-hbase-1.x</artifactId>
   <version>1.3.0</version>
        <exclusions>
        <exclusion>
            <groupId>com.google.guava</groupId>
            <artifactId>guava</artifactId>
        </exclusion>
        <exclusion>
            <groupId>com.google.api.grpc</groupId>
            <artifactId>grpc-google-common-protos</artifactId>
        </exclusion>
        <exclusion> 
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
        </exclusion>
        <exclusion> 
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
        </exclusion>
    </exclusions>
</dependency>

并尝试创建连接：

Connection connection = BigtableConfiguration.connect(projectID, instanceID));

当我运行代码时，我会收到以下堆栈跟踪：

java.lang.IllegalStateException: Could not find an appropriate constructor for com.google.cloud.bigtable.hbase1_x.BigtableConnection
at com.google.cloud.bigtable.hbase.BigtableConfiguration.connect(BigtableConfiguration.java:128)
at com.google.cloud.bigtable.hbase.BigtableConfiguration.connect(BigtableConfiguration.java:113)

这个issue 建议可以通过设置环境变量GOOGLE_APPLICATION_CREDENTIALS 来解决这个问题。我已将其设置为 systen 上的环境变量和 Eclipse 运行配置上的 maven 设置，但仍然收到相同的错误。

感谢收看。

更新

请求的堆栈跟踪更长。请不要被提到的数据流误导，这是试图以标准方式访问 BigTable，而不是作为数据流管道的一部分。

Answer 1

堆栈跟踪最相关的部分在这里：

Caused by: java.lang.NoSuchMethodError: com.google.cloud.bigtable.config.BigtableOptions$Builder.setAdminHost(Ljava/lang/String;)Lcom/google/cloud/bigtable/config/BigtableOptions$Builder;
at com.google.cloud.bigtable.hbase.BigtableOptionsFactory.fromConfiguration(BigtableOptionsFactory.java:301)

从这些行中，我们可以看到在 bigtable-hbase jar 中声明的 BigtableOptionsFactory 正在尝试调用在 bigtable-client-core 中声明的 BigtableOptions.setAdminHost。给定NoSuchMethodError，这意味着当我们在 1.3.0 编译 bigtable-hbase jar 时，BigtableOptions.setAdminHost 方法在 bigtable-client-core 1.3.0 jar 中可用。因此，您的两个 jar 版本很可能不匹配。事实上，setAdminHost 是在 https://github.com/googleapis/java-bigtable-hbase/commit/6c0756973b12e5fd2a9546a49342bb7e96ae28b3 中作为方法添加的，它在 1.1.0 版本中被合并，所以你的 bigtable-client-core 可能是之前的版本。你能验证一下吗？
