GetSchema for DB plugins does not work when a newer version of the same plugin is added. Here is the scenario that failed.
1. GetSchema on DB plugin v1.6.0 (works)
2. Deploy newer DB plugin v1.6.1
3. Perform getSchema on same table
This operation doesn't work. and fails with the following stacktrace
This was fixed as part of CDAP-5715. Tested this to be working. Closing it as duplicate.
