Ah, there's _another_ deadlock: finishing a FileWriter closes the underlying file. This is done as a continuation that runs on the I/O thread pool (I think). (On a side note, would anyone complain if I #ifdef'd in the pthread calls to name threads on Linux to make debugging easier?) On S3, closing a file blocks on a condition variable until all background writes are finished…and of course, those background writes are on the I/O thread pool, like everything else, so we hang. -- This is an automated message from the Apache Git Service.
