Jozef Vilcek updated BEAM-9420:
-------------------------------
Description:
If bootstrap brokers does contain an unhealthy server, it can break the start
of a whole Beam job. During the start, `KafkaUnboundedReader` is waiting for
`setupInitialOffset()`. Wait timeout is either a double time of `request.
timeout.ms` or some default constant. In both cases, it might not be enough
time for kafka-client to initiate fallback and retry metadata discovery via
another broker from given bootstrap list.
The client should be able to specify timeout for `setupInitialOffset()`
explicitly as a setting to KafkaIO read.

If bootstrap brokers does contain an unhealthy server, it can break the start
of a whole Beam job. In such case, `KafkaUnboundedReader` is waiting for
`setupInitialOffset()`. In case `request. timeout.ms` is not specified it waits
some default amount or double of the timeout value. In both cases, it might not
be enough time for kafka-client to initiate fallback and retry metadata
discovery via another broker from given bootstrap list.
The client should be able to specify timeout for `setupInitialOffset()`
explicitly as a setting to KafkaIO read.
