> Write data to Kafka continuously from Hive hook - can do this by writing a script that constantly creates tables. Bring down the Active instance with kill -9. Ensure writes continue after passive becomes active. The expectation is the number of tables created and the number of tables in Atlas match.
> In one test, wrote 180 tables and switched over 6 times from one instance to another. Found that 1 table was lost of the lot. i.e. 179 tables were created, and 1 did not get in.
