我最近开始研究 NoSql 和大数据，并决定继续研究它们。从几天开始，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，我在安装的每个阶段都有不同的错误。在这方面，我正在关注下面提到的教程。

对于 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，我在那里看不到 datanode，这些值仅存在：

$ jps
3984 NameNode
6864 Jps
5972 JobTracker

但是，当我导航到这个地址 127.0.0.1:50070 时，它运行良好。但是当我尝试运行测试 wordcount 示例作业时，它在下面提到的位置停留了很长时间，我必须重新启动 cygwin 终端：

2013 年 11 月 6 日 13:43:01 信息 mapred.JobClient：正在运行的作业：job_201005081732_0001 2013 年 11 月 6 日 13:43:02 信息 mapred.JobClient：地图 0% 减少 0%

此外，我只是忽略了它并转移到在 Hadoop 之上安装和配置 Hbase，安装进行得很好，但是现在当我在 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 ERROR :
org.apache.hadoop.hbase.MasterNotRunningException: 重试 7 次如果我运行 Scan 'test' 命令，我得到 ERROR:
org.apache.hadoop.hbase.client.NoServerForRegionException: Unable to find region for test,,,99999999999999 after 7尝试。

我真的不知道该怎么办，我一直在寻找几天，但仍然找不到我的错误的确切解决方案。

为了成功配置 Hadoop 和 Hbase，我真的需要在这方面为各位专家提供帮助。

这是我的 DataNode 日志：

创建一个目录，比如说/home/hadoop/workspace/temp_dir并将hadoop.tmp.dir具有此目录的属性作为其值添加到您的core-site.xml文件中。/home/hadoop/workspace/data_dir然后把and的权限改成/home/hadoop/workspace/temp_dir755，重启Hadoop。
