László Bodor updated HIVE-28822:
--------------------------------
Description:
Concurrent `INSERT INTO` statements that create the same new dynamic partition
on an external non-ACID Hive table backed by S3 can fail with `MoveTask return
code 40000`. The root cause is a check-then-rename race in `Hive.mvFile`'s
`_copy_N` naming loop: two writers pick the same destination path between an
`exists()` probe and the subsequent `rename()` call, and the loser gets a
`FileAlreadyExistsException` from `S3AFileSystem.initiateRename`.
This is separate from HIVE-29744, which addresses the *silent* data-loss twin
of this race (concurrent writers overwriting each other with no error). This
ticket is specifically about the *fail-loud* variant that survives even after
HIVE-29744.
Local repro against table on S3 gave:
