-----------------------------------
Summary: Producer should only timeout a batch in the accumulator
when metadata is missing.
Key: KAFKA-3388
URL: https://issues.apache.org/jira/browse/KAFKA-3388
Project: Kafka
Issue Type: Bug
Affects Versions: 0.9.0.1
Reporter: Jiangjie Qin
Priority: Blocker
Fix For: 0.10.0.0
In KIP-19 we are reusing the request.timeout.ms to timeout the batches in the
accumulator. We were intended to avoid the case that the batches sitting in the
accumulator forever when topic metadata is missing.
Currently we are not checking if metadata is available or not when we timeout
the batches in the accumulator (although the comments says we will check the
metadata). This causes problem that once the previous batch hit a request
timeout and got retried, all the subsequent batches will fail with timeout
exception. We should only timeout the batches in the accumulator when the
metadata of the partition is missing.
