Doing that directly won¹t work at all. Because ORC files are only readable after the Footer is written out, which won¹t be for any open files. > I won¹t be able to test these scenarios till tomorrow and would like to >have some idea of what to expect this afternoon. If I remember correctly, your previous question was about writing ORC from Storm. If you¹re on a recent version of Storm, I¹d advise you to look at storm-hive/ https://github.com/apache/storm/tree/master/external/storm-hive Or alternatively, there¹s a ³hortonworks trucking demo² which does a partition insert instead.
