Description

 

An integer overflow occurs if a fairly large value is passed to --num-records.  It causes a NegativeArraySizeException error.

./bin/kafka-producer-perf-test.sh --topic=test --producer-props bootstrap.servers=localhost:9092 --num-records 2000000000000000 --throughput 1 --record-size 10
