Question

我正在尝试连接到远程HBase集群以检索数据，但客户端在同一个地方连续挂起：

我已经读完了，听起来它应该是客户端/服务器版本之间的差异，但我检查了我的版本：

-sh-4.1$ hbase version

我的pom.xml依赖项：

    <dependency>
        <groupId>org.apache.hbase</groupId>
        <artifactId>hbase</artifactId>
        <version>0.94.6</version>
    </dependency>
    <dependency>
        <groupId>org.apache.hadoop</groupId>
        <artifactId>hadoop-core</artifactId>
        <version>1.2.1</version>
    </dependency>

我也试过了：

<dependency>
  <groupId>org.apache.hadoop</groupId>
  <artifactId>hadoop-common</artifactId>
  <version>2.0.0-cdh4.3.0</version>
</dependency>

奇怪的是，当我在Netbeans IDE中运行它时，程序运行正常，但是当我尝试从另一台服务器运行它时，它就会挂起。有什么见解吗？

对于那些想知道的人，你必须使用cloudera jar。您可以将pom.xml的repo更改为cloudera：http://www.cloudera.com/documentation/enterprise/5-2-x/topics/cdh_vd_cdh5_maven_repo.html 或者您可以将jar用于/ opt / cloudera

Java - HBase客户端在会话建立完成后停留
