12.1 Adding Slave Servers

This section explains how to add slave servers after operations have started.

  1. Configuring Host Name Settings

  2. Registering the DFS Client Information

  3. Adding by Cloning

  4. Stopping Hadoop

  5. Remounting (Only if replicated configuration is used for the master server)

  6. Editing and Reflecting the Slave Server Definition File

  7. Changing Hadoop Configuration Parameters

  8. Starting Hadoop


The procedure for adding a slave server is shown below.

Use root permissions for all tasks in this procedure.

Note that the location for implementing the procedure outlined in "12.1.3 Adding by Cloning" will vary depending on the environment in which the additional slave server will be installed.

This section describes the procedure to install even more slave servers, in addition to those comprising the configuration built in "6.3 Adding Second and Subsequent Slave Servers" during initial installation, using the following environment as an example.

  • Representative partition

: /dev/disk/by-id/scsi-1FUJITSU_300000370106

  • File system ID

: 1

  • Mount point

: /mnt/pdfs

  • Master servers

: master1 (primary), master2 (secondary)

  • Slave servers already built during initial installation

: slave1, slave2, slave3, slave4, slave5

  • Slave server to be newly installed

: slave6

  • Other slave servers to be additionally installed

: slave7, slave8, slave9, slave10
