Description

Running "cargo publish" for the arrow-flight crate resulted in this error:

error: failed to run custom build command for `arrow-flight v0.16.0 (/home/andy/apache-arrow-0.16.0/rust/target/package/arrow-flight-0.16.0)`Caused by:
  process didn't exit successfully: `/home/andy/apache-arrow-0.16.0/rust/target/package/arrow-flight-0.16.0/target/debug/build/arrow-flight-1b2906a3933d2832/build-script-build` (exit code: 1)
--- stderr
Error: Custom { kind: Other, error: "protoc failed: ../../format: warning: directory does not exist.\nCould not make proto path relative: ../../format/Flight.proto: No such file or directory\n" }
 

The workaround was to edit the build.rs and make the path absolute and then run "cargo publish --allow-dirty", but we should find a better solution before the next release.
