------------------------------------
Summary: KAFKA-15665 prevents safe reassignments from completing
Key: KAFKA-19736
URL: https://issues.apache.org/jira/browse/KAFKA-19736
Project: Kafka
Issue Type: Bug
Reporter: Alyssa Huang
The implementation for KAFKA-15665 is a little too strict - it requires that
all replicas in the target replica set be in ISR.
This means if we have a reassignment like [1, 2, 3] -> [2, 3, 4] where broker 2
was unhealthy and lagging in replication, reassignment would not complete.
