-----------------------------------

             Summary: kafka-reassign-partitions command should give a better 
error message when a topic does not exist
                 Key: KAFKA-12329
                 URL: https://issues.apache.org/jira/browse/KAFKA-12329
             Project: Kafka
          Issue Type: Improvement
            Reporter: David Jacot
            Assignee: David Jacot


The `kafka-reassign-partitions` command spits out a generic when the 
reassignment contains a topic which does not exist:

{noformat}
$ ./bin/kafka-reassign-partitions.sh --bootstrap-server localhost:9092 
--execute --reassignment-json-file reassignment.json
Error: org.apache.kafka.common.errors.UnknownTopicOrPartitionException: This 
server does not host this topic-partition.
{noformat}

When the reassignment contains multiple topic-partitions, this is quite 
annoying. It would be better if it could at least give the concerned 
topic-partition.
