----------------------------------
Summary: 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
