when using Kafka Connect to send data to Kafka
[ https://issues.apache.org/jira/browse/KAFKA-8120?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17098935#comment-17098935 ]
Jun Wang commented on KAFKA-8120:
---------------------------------
Steps to reproduce and verify with kafka 2.5
1. run attached gen-mongodump.sh to create a dummy monodump file arround 1.2G
2. increase the initial heap size to 4G in bin/connect-standalone.sh
{noformat}
if [ "x$KAFKA_HEAP_OPTS" = "x" ]; then
export KAFKA_HEAP_OPTS="-Xms4G -Xmx8G"
fi{noformat}
3. add batch.size=1 parameter in config/connect-file-source.properties
{noformat}
batch.size=1
{noformat}
4. start zookeeper-server and kafka-server if not yet
5. start kafka connect in standalone mode with following parameters
{noformat}
bin/connect-standalone.sh config/connect-standalone.properties config/connect-file-source.properties config/connect-file-sink.properties
{noformat}
within one minute, you will see following error.

6. Run extra test with attached test.txt, In this test case kafka connect only process 6 lines out of 100 lines file.
This extra test case is not rated to the issue reported. but I found and fixed.
