hbase客户端api在table.get(row)处卡住，

我正在使用hbase的本地api编写一个hbase java客户机。
我可以连接到hbase并使用我创建的hbase客户端运行各种查询。我用“hbase classpath”命令运行了hbase客户机。它解决了所有的依赖关系。
现在我们希望这个hbase客户机成为项目的一部分，该项目将它作为其组件之一。因此，在集成它之后，我们需要将它作为项目war文件的一部分来运行（我们需要将它作为restapi的一部分来运行）。我添加了hbase-site.xml。hdfs-site.xml和core-site.xml作为资源，并设置为配置对象的资源。

Configuration conf = HBaseConfiguration.create()

URL hbaseUrl=HbaseManagerServiceImpl.class.getClassLoader().getResource("hbase-site.xml");
conf.addResource(hbaseUrl.toString());
URL hdfsUrl=HbaseManagerServiceImpl.class.getClassLoader().getResource("hdfs-site.xml");
conf.addResource(hdfsUrl.toString());
URL coreUrl=HbaseManagerServiceImpl.class.getClassLoader().getResource("core-site.xml");
conf.addResource(coreUrl.toString());

当我试图只添加core-site.xml时，我得到了一个错误，错误是“include failed”该主机上存在哪个文件，所以在resource older中也添加了这个文件，解决了我的问题。

HTable table = new HTable(conf , "tableName");

我可以成功地执行扫描和获取行操作并获取结果。

Scan scanTable = new Scan();
Get row = new Get(key);

但是当我尝试执行“result rowdata=table.get（row）；”
我的代码卡住了，没有显示任何错误。
我可以用“hbase classpath”命令运行相同的代码。我需要设置$hadoop\u classpath和$hbase\u classpath变量吗？我正在jettywebserver上运行我的代码。
以下是错误跟踪：

我现在可以解决这个问题了。hbase-site.xml和其他*-site.xml没有正确地注入到java代码中，所以我不得不做以下更改。

URL hbaseSite=HbaseManagerServiceImpl.class.getClassLoader().getResource("hbase-site.xml");

InputStream inputHbase = new URL(hbaseSite.toString()).openStream();

conf.addResource(inputHbase);

我检查了输入的xml文件是否正确，我试图打印输入文件的内容。

String inputLine;
        while ((inputLine = in.readLine()) != null)
            System.out.println(inputLine);
        in.close();

首先，检查hbase-site.xml文件中的clientport：

<property>
  <name>hbase.zookeeper.property.clientPort</name>
  <value>2222</value>
</property>

在java程序中：必须将clientport设置为与hbase-site.xml文件中的相同：

Configuration config = HBaseConfiguration.create();
config.set("hbase.zookeeper.property.clientPort", "2222");
