Learn the new Parcel format for installing and upgrading CDH and other Hadoop ecosystem components. Parcels enable the new rolling upgrade functionality in Cloudera Manager, provide rollback functionality, and make maintenance windows short and painless. In this e-learning module, we discuss the benefits of Parcels, compare Parcels and packages, and understand what a Parcel file contains. The module finishes with a complete demonstration of a CDH upgrade and several component installations, including Cloudera Impala and Cloudera Search.
