This page documents the incompatible changes between CDAP 4 and CDAP 5.
| Change | Impact | CDAP 5 Behavior |
|---|
No centralized management of dataset modules, types, jars | - Cannot use dataset classes that are not included in the same application artifact
- Explore service won't able to instantiate dataset instance for
RecordScannable / RecordWritable implementations- Only affect
Table based dataset, not affecting FileSet based dataset
| - Dataset classes should always be inside the application artifact jar
- Need to provide cdap-hive jar to be added to Hive service to query Table
- Explore integration will be off in cloud runtime
|
| Default tx control for program will be explicit (except Flow) | - Transactional operations need to be wrapped with
Transactional.execute
| - In cloud runtime, calling
Transactional.execute will result in exception - Would still works if runs with default profile
|
| No custom log pipeline for programs in cloud | - Logs collection will be done via cloud service directly, and won't go through CDAP
| - It will still works for runs using default profile
|
| No dynamic access to artifact store | - API will be removed / deprecated
| - New API only available for cdap system extensions
- Only services running with default profile have access
