Configuring Local Package and Parcel Repositories
Cloudera hosts parcel repositories and package repositories that you can use to install software products such as Cloudera Manager or Cloudera Runtime. While Cloudera-hosted repositories serve most installations effectively, certain deployment scenarios require custom, internal repository configurations.
For example, using the Cloudera-hosted software repositories
requires client access over the Internet. Typical installations use the latest available
software. In some scenarios, these behaviors might not be desirable, such as:
- You need to install older product versions. For example, in a Cloudera Runtime cluster, all hosts must run the same Cloudera Runtime version. After completing an initial installation, you may want to add hosts. This could be to increase the size of your cluster to handle larger tasks or to replace older hardware.
- The hosts on which you want to install Cloudera products are not connected to the Internet, so they cannot reach the Cloudera repository (for a parcel installation, only the Cloudera Manager Server needs Internet access, but for a package installation, all cluster hosts require access to the Cloudera repository). Most organizations partition parts of their network from outside access. Isolating network segments improves security, but can add complexity to the installation process.
