Managing Software Distribution
A major function of Cloudera Manager is to distribute and activate software in your cluster. Cloudera Manager supports two software distribution formats: packages and parcels.
A package is a binary distribution format that contains compiled code and meta-information such as a package description, version, and dependencies. Package management systems evaluate this meta-information to allow package searches, perform upgrades to a newer version, and ensure that all dependencies of a package are fulfilled. Cloudera Manager uses the native "system package manager" for each supported OS.
- Parcels are self-contained and installed in a versioned directory. This means that multiple versions of a given parcel can be installed side-by-side. You can then designate one of these installed versions as the active one. With traditional packages, only one package can be installed at a time so there's no distinction between what's installed and what's active.
- Parcels can be installed at any location in the filesystem. By default, parcels are installed in /opt/cloudera/parcels.
