----------------------------------------
Summary: Integrate controlled shutdown into kafka shutdown hook
Key: KAFKA-927
URL: https://issues.apache.org/jira/browse/KAFKA-927
Project: Kafka
Issue Type: Bug
Reporter: Sriram Subramanian
Assignee: Sriram Subramanian
The controlled shutdown mechanism should be integrated into the software for
better operational benefits. Also few optimizations can be done to reduce
unnecessary rpc and zk calls. This patch has been tested on a prod like
environment by doing rolling bounces continuously for a day. The average time
of doing a rolling bounce with controlled shutdown for a cluster with 7 nodes
without this patch is 340 seconds. With this patch it reduces to 220 seconds.
Also it ensures correctness in scenarios where the controller shrinks the isr
and the new leader could place the broker to be shutdown back into the isr.
