| Extensions should include a folder with the extension name. |
| Subfolders of the extension name folder represents different |
| extension versions. |
| |
| For a sample extension MY_EXT 1.0, I would create subfolders: MY_EXT/1.0 |
| |
| Within each extension version folder, there should be both a metainfo.xml |
| file and a services folder. The metainfo.xml should contain the |
| stack versions with which the extension version are compatible. |
| |
| For example the following metainfo.xml shows an extension that is |
| compatible with both HDP 2.4 and HDP 2.5: |
| |
| <metainfo> |
| <prerequisites> |
| <min-stack-versions> |
| <stack> |
| <name>HDP</name> |
| <version>2.4</version> |
| </stack> |
| <stack> |
| <name>HDP</name> |
| <version>2.5</version> |
| </stack> |
| </min-stack-versions> |
| </prerequisites> |
| </metainfo> |
| |
| The services folder will contain all services that are part of the |
| extension version. The contents of those service folders will be the |
| same as what you would find in under a stack version's services folder. |
