hadoop集群处理

0基础搭建Hadoop大数据处理-集群安装

假如说Hadoop集群已经运行了一段时间。建议采用第二种。第二种方案如下：1）修改每个Slave的namespaceID使其与Master的namespaceID一致。或者 2）修改Master的namespaceID使其与Slave的namespaceID一致。该"namespaceID"位于"/usr/hadoop/...

2.3.5 配置Hadoop环境要在所有机器上配置Hadoop，首先在NameNode上进行配置，执行如下的解压缩命令：$tar –xzvf/home/hadoop/hadoop-1.2.1.tar.gz Hadoop的配置文件主要存放在hadoop安装目录下的conf目录中,主要有以下几个配置文件要修改:...

hadoop下线一个节点，整个集群就卡，怎么处理呢，能动态下线限速吗？
