Ok, we should have documented that call in the user docs better. Sorry about that!
The JavaDoc is probably better documentation: https://github.com/apache/orc/blob/master/java/core/src/java/org/apache/orc/OrcFile.java#L773 I must not have updated the Javadoc on the website when I rolled ORC's 1.3 release. OrcFile.readerIsCompatible is the code that figures out whether two files can be merged together or not. Basically, the footers of the files have to be compatible with each other. ..
