------------------------------
Summary: BrokerChangeListener computes inconsistent live/dead
broker list
Key: KAFKA-3085
URL: https://issues.apache.org/jira/browse/KAFKA-3085
Project: Kafka
Issue Type: Bug
Components: core
Affects Versions: 0.9.0.0
Reporter: Jun Rao
On a broker change ZK event, BrokerChangeListener gets the current broker list
from ZK. It then computes a new broker list, a dead broker list, and a live
broker list with more detailed broker info. The new and live broker list are
computed by reading the value associated with each of the current broker twice.
If a broker is de-registered in between, these two list will not be consistent.
