--------------------------------------
Summary: Broker fails to parse Null Metadata in OffsetCommit
requests
Key: KAFKA-3394
URL: https://issues.apache.org/jira/browse/KAFKA-3394
Project: Kafka
Issue Type: Bug
Components: core
Affects Versions: 0.10.0.0
Reporter: Magnus Edenhill
librdkafka sends a Null Metadata string (size -1) in its OffsetCommitRequests
when there is no metadata, this unfortunately leads to an exception on the
broker that expects a non-null string.
