Hey Allesandro, Welcome to the community! Currently ORC has a hard dependency on the Hadoop FS -- so the easiest way to use the Writer would be to directly write to disk. There is an ongoing effort to remove this (undeeded) dependency -- see ORC-508 <https://issues.apache.org/jira/browse/ORC-508> and a fairly recent PR <https://github.com/apache/orc/pull/641> by Owen if you want to hack around. An alternative would be to use a custom in-memory FS as we currently do for some tests <https://github.com/pgaref/orc/blob/master/java/core/src/test/org/apache/orc/impl/TestPhysicalFsWriter.java#L168> .
Hope this helps!
