Hadoop HDFS部署
[英]Hadoop HDFS Deployment
问题描述
I am trying to understand the relationship between HDFS and the various other constituents of a typical Hadoop cluster. 
我试图了解HDFS与典型Hadoop集群的其他各个组成部分之间的关系。 Is HDFS only supposed to be running on NameNodes and DataNodes , or is it running on every single node type ( MasterNode , SlaveNodes , ZooKeeperNode , etc.)? 是HDFS应该只是一个运行NameNodes和DataNodes ，或者是它的每一个节点类型运行（ MasterNode ， SlaveNodes ， ZooKeeperNode等）？

You can refer to the read/write process in Hadoop-The definitve Guide book. 您可以参考Hadoop-definitve指南书中的读/写过程。 No all data is stored on every node. 并非所有数据都存储在每个节点上。 There are few concepts to frequently monitor the process and interact accordingly. 很少有概念可以经常监视过程并进行相应的交互。 Please revisit your theoretical concepts. 请重温您的理论概念。 Happy learning 快乐学习
