Reading/writing into kafka within the integration test fails because of the

This requires further investigation.

We've observed in standalone integration tests that embedded kafka broker was
unreachable and kafka NetworkClient spams the logs with the following exception
messages.

{code}
Reading/writing into kafka within the integration test fails because of the
above problem.
Majority of the integration tests that fails with junit test timeout are due to
the following:
were stuck in the infinite retry loop of BrokerProxy I/O thread polling
messages from the embedded kafka broker(or trying to produce messages and
failing ).
This requires further investigation.
