Pardhu Madipalli commented on KAFKA-6764:
-----------------------------------------

I am observing this behavior with kafka broker with SSL enabled even with a new 
consumer group also. I produced a few messages. Then I created a new consumer 
with a new group. Then *kafka-console-consumer --from-beginning* is not 
displaying any messages. But when I tried with *--partition 0* I could see it 
reading the messages.

Then I killed my broker with ssl and created a new broker without ssl. This 
time, even if I did not specify *--partition 0*, I can see all the messages as 
expected.

In both the cases only a single broker is running. Topic partitions and 
replication factor are both 1.

> Per its usage statement, {{kafka-console-consumer.sh}} ignores 
> {{\-\-from-beginning}} when the specified consumer group has committed 
> offsets, and sets {{auto.offset.reset}} to {{latest}}. However, if 
> {{\-\-partition}} is also specified, {{\-\-from-beginning}} is observed in 
> all cases, whether there are committed offsets or not.
> This happens because when {{\-\-from-beginning}} is specified, {{offsetArg}} 
> is set to {{OffsetRequest.EarliestTime}}. However, {{offsetArg}} is [only 
> passed to the 
> constructor|https://github.com/apache/kafka/blob/fedac0cea74feeeece529ee1c0cefd6af53ecbdd/core/src/main/scala/kafka/tools/ConsoleConsumer.scala#L76-L79]
>  for {{NewShinyConsumer}} when {{\-\-partition}} is also specified. Hence, it 
> is honored in this case and not the other.
> This case should either be handled consistently, or the usage statement 
> should be modified to indicate the actual behavior/usage.
