In this case, you have a replication factor of 1. So, each partition has
only 1 replica.
There are two possibilities: (1) The producer didn't send all messages. (2)
The producer successfully sent all messages, but the consumer didn't
receive all messages. Could you first check the producer log and make sure
there are no errors? If so, check the consumer log. You should see sth like
"Consumer ???? selected partitions : ". See if all partitions are selected.
Also, check if there is any error in the consumer log.
To understand leader and isr, you can read the replication design inhttp://kafka.apache.org/08/design.html
