Planning Data Export

Scenarios

Before you use GDS to export data from a cluster, prepare data to be exported and plan the export path.

Planning an Export Path

  • Remote mode
  1. Log in to the GDS data server as user root and create the /output_data directory for storing data files.

    1
    mkdir -p /output_data

  2. (Optional) Create a user and the user group to which it belongs. This user is used to start GDS and must have the write permission on the directory for storing data files.

    1
2
    groupadd gdsgrp
useradd -g gdsgrp gdsuser

    If the following information is displayed, the user and user group already exist. Skip this step.

    1
2
    useradd: Account 'gdsuser' already exists.
groupadd: Group 'gdsgrp' already exists.

  3. Change the directory owner to gdsuser.

    1
    chown -R gdsuser:gdsgrp /output_data
