[jira] [Commented] (KAFKA-8120) Getting NegativeArraySizeException
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=17096659#comment-17096659 ]
Jun Wang commented on KAFKA-8120:
---------------------------------
Hi
I think [~ChrisEgerton] was right. The current logic of expanding the buffer is too aggressive. We could just expand the buffer only when the buffer does not extract a line.
I was able to reproduce similar issue KAFKA-4335, I am working the fix/refactoring FileStreamSourceTask. please assign this to me.
