   > Hi David, When I try to run JDBCReader I get URI has empty scheme 
java.lang.RuntimeException: URI has empty scheme: '/tmp at 
org.apache.arrow.dataset.file.JniWrapper.writeFromScannerToFile(Native Method) 
at 
org.apache.arrow.dataset.file.DatasetFileWriter.write(DatasetFileWriter.java:46)
 at 
org.apache.arrow.dataset.file.DatasetFileWriter.write(DatasetFileWriter.java:59)
 Any idea what could be causing this? Regards GP
   
   Hi @pronzato, this project also uses JDBC reader 
https://github.com/davisusanibar/java-python-by-cdata.git.
   
   Could you please try using that and confirm if it is also failing?
