--------------------------------
Summary: structured streaming fetched wrong current offset from
kafka
Key: KAFKA-7796
URL: https://issues.apache.org/jira/browse/KAFKA-7796
Project: Kafka
Issue Type: Bug
Components: consumer
Environment: Linux, Centos 7
Reporter: Ryne Yang
when running spark structured streaming using lib: `"org.apache.spark" %%
"spark-sql-kafka-0-10" % "2.4.0"`, we keep getting error regarding current
offset fetching:
{code:java}

for some reason, looks like fetchLatestOffset returned a Long.MIN_VALUE for one
of the partitions. I checked the structured streaming checkpoint, that was
correct, it's the currentAvailableOffset was set to Long.MIN_VALUE.
kafka broker version: 1.1.0.
lib we used:
{{libraryDependencies += "org.apache.spark" %% "spark-sql-kafka-0-10" % "2.4.0"
}}
how to reproduce:
basically we started a structured streamer and subscribed a topic of 4
partitions. then produced some messages into topic, job crashed and logged the
stacktrace like above.
also the committed offsets seem fine as we see in the logs:
{code:java}
=== Streaming Query ===
Identifier: [id = c46c67ee-3514-4788-8370-a696837b21b1, runId =
31878627-d473-4ee8-955d-d4d3f3f45eb9]
Current Committed Offsets: {KafkaV2[Subscribe[REVENUEEVENT]]:
{"REVENUEEVENT":{"0":1}}}
Current Available Offsets: {KafkaV2[Subscribe[REVENUEEVENT]]:
{"REVENUEEVENT":{"0":-9223372036854775808}}}
{code}
so spark streaming recorded the correct value for partition: 0, but the current
available offsets returned from kafka is showing Long.MIN_VALUE.
