> read orc when some of the columns are missing in some files
> ------------------------------------------------------------
>
> Key: SPARK-21019
> URL: https://issues.apache.org/jira/browse/SPARK-21019
> Project: Spark
> Issue Type: Bug
> Components: Input/Output
> Affects Versions: 2.1.1
> Reporter: Modi Tamam
>
> I'm using Spark-2.1.1.
> I'm experiencing an issue when I'm reading a bunch of ORC files when some of
> the fields are missing from some of the files (file-1 has fields 'a' and 'b',
> file-2 has fields 'a' and 'c'). When I'm running the same flow with JSON
> files format, every thing is just fine (you can see it at the code snippets ,
> if you'll run it...) My question is whether it's a bug or an expected
> behavior?
> I'v pushed a maven project, ready for run, you can find it here
> https://github.com/MordechaiTamam/spark-orc-issue.
