[jira] [Commented] (ARROW-4419) [Flight] Test Flight servers and clients with a generic gRPC services

    [ https://issues.apache.org/jira/browse/ARROW-4419?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16853080#comment-16853080 ] 

Wes McKinney commented on ARROW-4419:
-------------------------------------

OK, I just changed this JIRA to be that. I suppose we can write a test harness in Python that uses gRPC directly to make sure our custom message emitting/parsing is all compliant with the Protobuf protocol

> The Java implementation will fail to decode a schema message if the message also contains (empty) body buffers (see ArrowMessage.asSchema's precondition checks). However, clients using default Protobuf serialization will likely write an empty body buffer by default.
