我目前正在对HDFS和HBASE工作。 Hadoop和HBASE已正确安装在机器上，并且我的应用程序托管在同一台机器上时运行良好。HBASE错误：无法设置代理接口org.apache.hadoop.hbase.ipc.HRegionInterface
但是，当在另一台机器上托管。在第一次命中HBASE我得到一个错误说：
org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Servlet.service() for servlet [sitepulsewebsite] in context with path [/SitePulseWeb] threw exception [Request processing failed; nested exception is javax.jdo.JDODataStoreException
NestedThrowables:org.apache.hadoop.hbase.MasterNotRunningException: localhost:60000] with root cause
org.apache.hadoop.hbase.MasterNotRunningException: localhost:60000
而且在第二次打击我得到异常：
org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Servlet.service() for servlet [sitepulsewebsite] in context with path [/SitePulseWeb] threw exception [Request processing failed; nested exception is javax.jdo.JDODataStoreException: Failed setting up proxy interface org.apache.hadoop.hbase.ipc.HRegionInterface to localhost/127.0.0.1:60020 after attempts=1
NestedThrowables: org.apache.hadoop.hbase.client.RetriesExhaustedException: Failed setting up proxy interface org.apache.hadoop.hbase.ipc.HRegionInterface to localhost/127.0.0.1:60020 after attempts=1] with root cause
java.net.ConnectException: Connection refused
我的HBase-site.xml中读取如下：
<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://master:54310/hbase </value>
<description>
The directory shared by region servers. Should be
fully-qualified to
include the filesystem to use. E.g:
hdfs://NAMENODE_SERVER:PORT/HBASE_ROOTDIR
</description>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
<description>The mode the cluster will be in. Possible values are
false: standalone and pseudo-distributed setups with managed
Zookeeper
true: fully-distributed with unmanaged Zookeeper Quorum (see
hbase-env.sh)
</description>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>master</value>
<description>Comma separated list of servers in the ZooKeeper Quorum.
If HBASE_MANAGES_ZK is set in hbase-env.sh this is the list of
servers which we will start/stop ZooKeeper on.
</description>
</property>
<property>
<name>hbase.master</name>
<value>master:60010</value>
</property>
<property>
<name>hbase.zookeeper.property.clientPort</name>

更新日志 寻找由我的Java应用程序创建的日志（调试级别），我发现以下日志

在/ etc/hosts文件当映射从
127.0.0.1 localhost
改为
<my_server_IP> localhost
我的应用程序工作完全正常。因此我需要某种方式告诉应用程序连接到所需的主机名，而不是本地主机
我非常厌倦了调试它没有任何成功。
请帮我解决这个问题。任何形式的帮助将不胜感激。
在此先感谢
所以我很困惑。你解决了这个问题吗？事实证明有几件事导致了这个错误。 – 2012-01-15 16:52:29
不，我没有解决，我无法将本地主机映射到我的服务器的IP地址，因为当应用程序进入生产时，系统上运行的其他应用程序期望localhost将成为自我系统将会中断。 – devsri 2012-01-16 06:53:00
你禁用ipv6吗？ – 2012-01-16 15:30:31
