hadoop - Hbase HMaster 未运行

Question

我在 HBase 中遇到了一些问题。当我尝试启动 hadoop 时，它启动时没有任何问题。但 HBase 不工作。DataNode、HRegionServer、secondaryNameNode 等都在工作，但 HMaster 没有运行，当我启动 hbase 时。有时它会抛出异常“RegionServer 正在作为进程运行# xyz .先停止它。另一个奇怪的事情是 HBase 日志正在打印“Matser started”但是当我们检查时，它没有开始。我正在寻找问题，但无法理解。如果你有线索请指导我。这里是下面给出了 HBase 的日志

Answer 1

我认为，日志中的这一行，

2012-04-04 17:48:52,204 INFO org.apache.hadoop.ipc.Client: Retrying connect to server: localhost/127.0.0.1:54310. Already tried 0 time(s).

表示它正在连接到端口 54310 上的名称节点，但失败了。

能否请您在浏览器中输入此内容并告诉我您使用的准确端口以进行验证？

**http://localhost:50070**

您会在第一行看到类似 NameNode 'localhost:?' 的内容，而 '?' 是您的名称节点端口。
