Trouble Connecting to Remote HBase in Java

Question

I am trying to connect to a remote HBase from Java. hbase shell works fine. But when I try to connect in code I get errors. Here is my 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>

Here are what the errors look like:

java.net.ConnectException: Connection refused

Am I missing a value in my hbase-site.xml? If hbase shell works fine, why cant the code connect?

问题是我的hbase-site.xml不在我的类路径中。
