我正在尝试从 Java 连接到远程 HBase。hbase shell 工作正常。但是当我尝试在代码中连接时，我得到了错误。这是我的 hbase-site.xml

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

<configuration>

<property>
    <name>hbase.cluster.distributed</name>
    <value>true</value>
</property>

<property>
    <name>hbase.rootdir</name>
    <value>hdfs://some.ip.address:8020/hbase</value>
</property>

<property>
    <name>hbase.zookeeper.quorum</name>
    <value>some.ip.address</value>
</property>

<property>
    <name>hbase.coprocessor.user.region.classes</name>
    <value>org.apache.hadoop.hbase.coprocessor.AggregateImplementation</value>
</property>

<property>
    <name>hbase.rest.port</name>
    <value>9999</value>
</property>

</configuration>

以下是错误的样子：

我的 hbase-site.xml 中是否缺少值？如果 hbase shell 工作正常，为什么代码连接不上？

问题是我的 hbase-site.xml 不在我的类路径中。
