Summary: Track repair state for more reliable repair
Key: CASSANDRA-10302
URL: https://issues.apache.org/jira/browse/CASSANDRA-10302
Project: Cassandra
Issue Type: Improvement
Reporter: Yuki Morishita
Assignee: Yuki Morishita
During repair, coordinator and replica exchange various messages. I've seen
cases that those messages sometimes get lost.
We've made repair message to be more durable (CASSANDRA-5393, etc) but still
messages seem to be lost and hang repair till messaging timeout reaches.
We can prevent this by tracking repair status on repair participants, and
periodically check state after certain period of times to make sure everything
is working fine.
We alse can add command / JMX API to query repair state.
