--------------------------------------
Summary: [Java][FlightSql] flight-core and flight-sql jars
delivering same class names
Key: ARROW-17055
URL: https://issues.apache.org/jira/browse/ARROW-17055
Project: Apache Arrow
Issue Type: Improvement
Components: FlightRPC, Java
Reporter: Kevin Bambrick
Hello. I am trying to uptake arrow flight sql. We have a check in out build to
make sure that there are no overlapping class files in our project. When adding
the flight sql dependency to our project the warning throws that flight-sql and
flight-core overlap and the jars deliver the same class files.
Sample Warning: WARNING: CLASSPATH OVERLAP: These jars deliver the same class
files: [flight-sql-7.0.0.jar, flight-core-7.0.0.jar] files:
[org/apache/arrow/flight/impl/Flight$FlightDescriptor$1.class,
org/apache/arrow/flight/impl/Flight$ActionOrBuilder.class
It seems that the classes generated by Flight.proto gets generated in both
flight-sql and flight-core jars. Since these classes get generated in
flight-core, and flight-sql is dependent on flight-core, can the generation of
Flight.java and FlightServiceGrpc.java be removed from flight-sql and instead
rely on it to be pulled directly from flight-core?
thanks in advance!
