-------------------------------
Summary: remote_bootstrap should avoid starting the entire process
over again when `bootstrap_source` node crashes before remote_bootstrap
complete.
Key: KUDU-1550
URL: https://issues.apache.org/jira/browse/KUDU-1550
Project: Kudu
Issue Type: Improvement
Reporter: zhangsong
In current design and implementation, remote_bootstrap will start the entire
process again, when `bootstrap_source` node crashes before `remote_bootstrap`
complete. Instead, it will be better to continue remote_bootstrap from last
failed `position`.
1 it will save a lot of network and computation resource for remote_bootstrap.
2 it will save much time to recover when met `bootstrap_source` crash .
