Answer: Cloudera Manager support two software distribution formats

• Packages: Package is a binary distribution format which contains compiled code, meta-information, dependencies etc. Cloudera Manager uses the native system package manager for each supported OS.
• Parcels: Is a binary distribution format containing the program files, metadata etc.  

Parcels are self-contained and installed in a versioned directory, which 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 packages, only one package can be installed at a time so there is no distinction between what is installed and what is active. If you want to have Rolling Upgrade enabled then parcels are also required and package does not support the rolling upgrades.
