Open Issues
Data Router Publisher/Subscriber behaviour is not consistent
- On dr_publiser creation if we dont provide username/password a default usename/password is created, but the same is not happening for dr_subscriber.
- On dr_publisher creation if username/password is provided as part of input dmaap-dbc client Api returns username as output and password is defaulted ot "null".
- On dr_subscriber creation if we supply username/password as part of input dmaap-dbc client Api returns both username/password as null.
Cmpv2Certificates generation
- While testing with 5gbulkpm testcase Cmpv2Certificates processing is failing send mail for clarification.
**Further analysis is on going will be updating this wiki as we move along.
