连接到本地hbase时出错

我正试图通过一个java小程序连接到本地系统中安装的hbase（使用hortonworks 1.1.1.16），该程序执行下一个命令：

HBaseAdmin.checkHBaseAvailable(conf);

值得一提的是，使用 hbase 命令。
宿主文件的内容是下一个（其中 example.com 包含实际主机名）：

127.0.0.1 localhost example.com

hbase配置为在独立模式下工作：

hbase.cluster.distributed=false

执行程序时，将引发下一个异常：

这个痕迹提供了一些实际发生的事情的证据。似乎已经建立了与zookeeper的连接，但是当尝试访问主控时出现了故障。
虽然我花了几个小时试图在谷歌上找到一个解决方案，但我似乎并不例外。特别是，这个例外在两个方面与互联网上发现的大多数不同：
似乎每个人都有错误 getMaster attempt 0 of 1 failed 而不是 getMaster attempt 1 of 1 failed . 我不知道这是否有意义，但我觉得有点奇怪。
我找不到其他人 Broken pipe 错误。
顺便说一句，在hortonworks管理控制台中可以看到，master实际上正在运行。
查看最新日志时，输出如下：

2013-05-13 15:30:07,192 WARN org.apache.hadoop.ipc.HBaseServer: Incorrect header or version mismatch from 127.0.0.1:40788 got version 0 expected version 3

由于这是一个警告而不是一个错误，我不知道这是否与实际问题有关。每次执行时端口都不同。
非常感谢你的时间，我希望你能给这个问题带来一些启示。

最后我们发现了问题并解决了它。原来是个依赖性问题。我们用的是 hbase-0.95.0 以及 hbase-client-0.95.0 . 使用 hbase-0.94.7 或者 hbase-0.94.9 似乎有用。
然而，即使在hbase库的那个版本中，在某些情况下也会出现一些问题。特别是，在应用服务器（jbossas7）中运行它时会出现一些问题。最后，所有的问题似乎都可以通过移除依赖关系来解决 hbase-client-0.95.0 ，并替换为 haboop-core-1.1.2 因为hbase库中不包含的某些类是必需的。
当做。

我建议您首先检查您的hbase主/区域服务器端口是否与 netstat -n -a . 我遇到过这样的情况：hbase主ipc只绑定到外部ip（这是cloudera cdh），无法通过127.0.0.1访问它。看起来最有可能的情况是hbase shell在这种情况下仍然可以工作。
另一个可能的原因可能是以前的集群崩溃和一些hdfs数据损坏。在这种情况下，hbase实际上不会开始等待hdfs退出安全模式。但这看起来不是你的案子。如果是，您可以手动强制hdfs从控制台退出安全模式，然后执行以下操作 fsck 对于hadoop和hbase的类似过程。
