2.1. RPMs in the HDP repository

In the HDP repository, each component has two differenct source RPMs.

For example, for Hadoop, there are the following RPMs:

These different versions support different functions:

The src package is used to re-create the binary in a given environment. You can use the src package of a particular component if you want to rebuild RPM for that component.
The source package on the other hand, is used for reference or debuging purpose. The source package is particularly useful when you want to examine the source code of a particular component in a deployed cluster.
