Travis Crawford commented on HCATALOG-444:
------------------------------------------
Overall pretty good. I'm not super familiar with these interfaces and found the
doc useful.
Something that's not clear in the doc is how write failures are handled. For
example, are output written to a staging directory, then moved into place? Can
a worker task that crashes during writes restart and rewrite the data without
getting duplicates? Is there a "commit" or "close" type operation to signal all
writers have completed writing?
