Hadoop＆amp; Hbase安装和配置窗口上单个节点群集中的问题

标签： hadoop hbase apache-zookeeper

我最近开始研究NoSql和大数据，并决定继续研究它们。几天来，我试图在我的win2008 R2 64位机器上安装和配置Hadoop和Hbase。但不幸的是我没有成功，我在每个安装阶段都有不同的错误。我在这方面遵循下面提到的教程。

表示Hadoop = http://blog.sqltrainer.com/2012/01/installing-and-configuring-apache.html 对于Hbase = http://ics.upjs.sk/~novotnyr/blog/334/setting-up-hbase-on-windows

首先，当我在/ usr / local / hadoop目录中运行jps命令时，我没有看到datanode，这些值只有：

$ jps
3984 NameNode
6864 Jps
5972 JobTracker

但是，当我导航到这个地址127.0.0.1:50070时，它运行正常。但是当我尝试运行测试wordcount示例Job时，它长时间停留在下面提到的位置，我必须重新启动cygwin终端：

11/06/13 13:43:01 INFO mapred.JobClient：正在运行的工作：job_201005081732_0001 11/06/13 13:43:02 INFO mapred.JobClient：map 0％reduce 0％

此外，我只是忽略它并移动到Hadoop顶部安装和配置Hbase，安装顺利但现在当我在hbase shell中运行不同的命令时，我收到不同的错误，例如，如果我运行“list”命令，我得到错误：
org.apache.hadoop.hbase.MasterNotRunningException：重试7次 如果我运行Scan'test'命令，则会出现ERROR：
org.apache.hadoop.hbase.client.NoServerForRegionException：7次尝试后无法找到测试区域，99999999999999。

我真的不知道该怎么做，我一直在寻找几天，但仍然找不到我错误的确切解决方案。

为了成功配置Hadoop和Hbase，我真的需要为您提供帮助。

这是我的DataNode日志：

创建一个目录，比如/home/hadoop/workspace/temp_dir，并将属性hadoop.tmp.dir作为其值添加到core-site.xml文件中。然后将/home/hadoop/workspace/data_dir和/home/hadoop/workspace/temp_dir的权限更改为755并重新启动Hadoop。
