[feature #43107371]
I did the following:
Copied Avro read/persistent stuff from Sweeper Hobbits here.
Added the subscribe widget to the home. It appears on button right click of the map. We need to get this tuned, then fine tuned.
Added hbase and hadoop dependencies for compile time. So far does not cause any issues. HBase is provided in TomEE's lib, if not TomEE gives a lot of strange errors and fails to start itself (tomee, manager) properly.
Avro classes(CRUD) will be renamed into utility for HBase. Maybe we can use CRUDLocal. Right now they are just test cases.
The emailed messages for the users upon account signup have changed. We need to test this further.
