Default instructions will not work without the addition of -output-eventhubs false

[guilhemmarchand]

The default instructions in the README show 3 examples:

java -jar build/libs/kafka-data-gen.jar -message-count 20000000 -message-size 256 -topic kafka-demo -bootstrap.servers "localhost:9092" -acks all -kafka-retries 0 -kafka-batch-size 60000 -kafka-linger 1 -kafka-buffer-memory 33554432 -eps 10000

java -jar build/libs/kafka-data-gen.jar -message-count 20000000 -message-size 256 -topic kafka-demo -bootstrap.servers "localhost:9092" -acks all -kafka-retries 0 -kafka-batch-size 60000 -kafka-linger 1 -kafka-buffer-memory 33554432 -eps 0

java -jar build/libs/kafka-data-gen.jar -message-count 10 -message-size 256 -topic kafka-demo -bootstrap.servers "localhost:9092" -acks all -kafka-retries 0 -kafka-batch-size 60000 -kafka-linger 1 -kafka-buffer-memory 33554432 -eps 0 -generate-kafka-headers true -header-gen-profile 0

However this does not work and generates the following message in data-gen.log:

2020-09-09 10:16:43,068 INFO g.DataGenerator [main] Starting Kafka Data Generator
2020-09-09 10:16:43,094 INFO g.DataGenerator [main] Parsing CLI arguments
2020-09-09 10:16:43,095 ERROR g.DataGenerator [main] Output to Kafka and Output to EventHubs can't be enabled/disabled at the same time

If I had at the end of the command the following arguments then this works:

-output-eventhubs false -output-kafka true -output-stdout false

Example:

java -jar build/libs/kafka-data-gen.jar -message-count 20000000 -message-size 256 -topic kafka-demo -bootstrap.servers "localhost:19092" -acks all -kafka-retries 0 -kafka-batch-size 60000 -kafka-linger 1 -kafka-buffer-memory 33554432 -eps 0 -output-eventhubs false -output-kafka true -output-stdout false

Thanks
