Fully distributed: the use of multiple clusters fully distributed

Review (Review)

  Basic environment:

  Deployment configuration:

      DN:slaves:node01

      SNN:hdfs-site.xml: dfs.namenode.secondary.http.address   node01:50090

    2) details of the configuration when starting role

      dfs.namenode.name.dir

      dfs.namenode.data.dir

  Initialization & Start

    format

      FsImage

      VERSION

      Load our configuration file

      Tight manner by ssh-free start the appropriate role

  Pseudo-distributed to a fully distributed: the role of re-planning

Thinking

  • infrastructure
  • Deployment Configuration
  • Initialization run
  • Use the command line

step
