我正在使用hbase的原生API编写Hbase Java客户端。
我可以使用我创建的Hbase客户端连接到hbase并运行各种查询。我使用“hbase classpath”命令运行我的hbase客户端。这解决了所有依赖关系。
现在我们希望这个hbase客户端成为项目的一部分，并将其作为其组件之一。 因此，在集成之后，我们需要将其作为项目的War文件的一部分运行（我们需要将其作为rest API的一部分运行）。 我添加了hbase-site.xml。 hdfs-site.xml和core-site.xml作为资源，并设置为Resource to configuration object。
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());
当我尝试仅添加core-site.xml时，我收到错误说“包含失败”该主机上存在哪个文件，因此在资源较旧时添加了该文件，这解决了我的问题。
HTable table = new HTable(conf , "tableName");
我可以成功扫描并获取行操作并获取结果。
Scan scanTable = new Scan();
Get row = new Get(key);
但是当我尝试做“Result rowData = table.get（row）; “
我的代码卡住了，不会显示任何错误。
我可以使用“”hbase classpath“命令运行相同的代码。 我是否也需要设置$ HADOOP_CLASSPATH和$ HBASE_CLASSPATH变量，我通过jetty webserver运行我的代码。
以下是错误跟踪：

我现在能够解决这个问题。 hbase-site.xml和其他* -site.xml未在java代码中正确注入，因此我必须在下面进行更改。
URL hbaseSite=HbaseManagerServiceImpl.class.getClassLoader().getResource("hbase-site.xml");
InputStream inputHbase = new URL(hbaseSite.toString()).openStream();
conf.addResource(inputHbase);
我检查了是否输入了正确的xml文件我试图打印输入文件内容。
String inputLine;
while ((inputLine = in.readLine()) != null)
System.out.println(inputLine);
in.close();

<property>
<name>hbase.zookeeper.property.clientPort</name>
<value>2222</value>
</property>
Configuration config = HBaseConfiguration.create();
config.set("hbase.zookeeper.property.clientPort", "2222");
