---------------------------------
Summary: RocksDB segments not removed when store is closed causes
re-initialization to fail
Key: KAFKA-6360
URL: https://issues.apache.org/jira/browse/KAFKA-6360
Project: Kafka
Issue Type: Bug
Components: streams
Affects Versions: 1.1.0
Reporter: Damian Guy
Assignee: Damian Guy
Priority: Blocker
Fix For: 1.1.0

are not removed from the list of segments. So when the store is re-initialized
the old closed segments are used. This results in:
