Jason Gustafson updated KAFKA-8152:
-----------------------------------
Description:
Currently when the controller starts up, only the state of online partitions
will be sent to other brokers. Any broker which is started or restarted after
the controller will see only a subset of the partitions of any topic which has
offline partitions. If all the partitions for a topic are offline, then the
broker will not know of the topic at all. As far as I can tell, the bug is the
fact that `ReplicaStateMachine.startup` only does an initial state change for
replicas which are online.
This can be reproduced with the following steps:
# Startup two brokers
# Create a single partition topic with rf=1
# Shutdown the broker where the replica landed
# Shutdown the other broker
# Restart the broker without the replica
# Run `kafka-topics --describe --bootstrap-server \{server ip}`
Note that the metadata inconsistency will only be apparent when using
`bootstrap-server` in `kafka-topics.sh`. Using zookeeper, everything will seem
normal.
