Thanks for starting this proposal. I think there are still many issues for data transfer for pipeline recovery from my practice, which includes both basic function and performance. IIRC, there are only timeout exception and one no explicit meaning exception, thus client has no helpful information (such src node or target node meet issue, or other exceptions) to make decision. Back to this PR, I totally agree to throw exception from datanode to client first(but I am not sure if it is enough at this PR, maybe we need more information) then add more fault-tolerant logic at client side. IMO, we should file one new JIRA to design/refactor fault-tolerant for data transfer of pipeline recovery. Just my own suggestion, not blocker. -- This is an automated message from the Apache Git Service.
