Dong Lin commented on KAFKA-3145:
---------------------------------
[~zhiwei], yeah I understand that CPU usage depends the performance of the
machine. But I couldn't reproduce the NullPointerException using the latest
trunk.
I used kafka with git hash d7fc7cf6154592b7fea494a092e42ad9d45b98a0 without
chaning any file. The zookeeper, broker and producer are started as shown below:
zookeeper-server-start.sh config/zookeeper.properties
kafka-server-start.sh config/server.properties
kafka-producer-perf-test.sh --topic test --num-records 1000000 --record-size
100 --throughput 100000 --producer-props bootstrap.servers=localhost:9095.
If you are able to reproduce the NullPointerException, can you tell me the
following information:
- the git hash value of kafka you used
- The commands you used to start producer and broker.
Thanks,
