--------------------------------
Summary: PublishKafka and PublishKafka_0_10 hang indefinitely,
continually sending the same message, if delimiter ends at 8 KB mark
Key: NIFI-3182
URL: https://issues.apache.org/jira/browse/NIFI-3182
Project: Apache NiFi
Issue Type: Bug
Components: Extensions
Reporter: Mark Payne
If PublishKafka is configured to send using a delimiter, and it receives a
FlowFile whose content contains the delimiter, and that delimiter ends at the 8
KB mark (8192 bytes into the FlowFile Content), then PublishKafka will get
stuck in an infinite loop, sending the same message over and over.
To replicate, create a simple Flow:
GenerateFlowFile -> ReplaceText -> PublishKafka
For GenerateFlowFile, generate a message that is 8187 bytes.
With ReplaceText, configure it to always append the value "HELLO" (without
quotes).
Configure PublishKafka to use a demarcator of "HELLO" (without quotes).
When PublishKafka attempts to send the data, it will continually send the
randomly generated data over and over and over, never relinquishing its thread.
