[ https://issues.apache.org/jira/browse/ORC-152?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=16289027#comment-16289027 ] Alexandre Borgoltz commented on ORC-152: Hi Nicholas, I know this is getting a bit old now but... Have you discussed this problem (the ORC DataFrameWriter for an empty DataFrame does not write any .orc file hence losing the schema/structtype from the source...) with the spark project eventually? Any link/ref?
