[jira] [Created] (ARROW-8181) [Java][FlightRPC] Expose transport error metadata

Ryan Murray created ARROW-8181:
----------------------------------

             Summary: [Java][FlightRPC] Expose transport error metadata
                 Key: ARROW-8181
                 URL: https://issues.apache.org/jira/browse/ARROW-8181
             Project: Apache Arrow
          Issue Type: Task
          Components: Java
            Reporter: Ryan Murray
            Assignee: Ryan Murray


Flight currently do not make the gRPC trailer available when a FlightRuntimeException is called. This precludes using the richer error model discussed in [1][2]. The metadata in the gRPC trailer should be exposed in a protocol agnostic way. 

This task is to expose error metadata without exposing transport implementation specifics.
