Is this currently possible?\r\n\r\nI see that calling `.open()` on a `luigi.LocalTarget' class returns a `luigi.file.atomic_file`. Will that atomic_file behave like any other ordinary open file buffer? \r\n\r\nIt would be great to be able to use [odo] (https://github.com/blaze/odo) to do writes to luigi targets. I'm using [blaze](https://github.com/blaze/blaze) to run queries in my tasks. \r\n\r\nThanks! \r\n"}}
