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。
