在Java中连接到远程HBase时遇到问题

Question

我试图从Java连接到远程HBase。 hbase外壳工作正常。但是当我尝试在代码中连接时，我收到错误。这里是我的HBase-site.xml中

<?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> 

这里是错误的样子：

我失去了我的HBase-site.xml中的值？如果hbase shell工作正常，为什么不能连接代码？

Answer 1

问题是我的hbase-site.xml不在我的类路径中。
