Work Description: angoenka edited a comment on issue #5971: [BEAM-4800]
Fix artifact staging test
URL: https://github.com/apache/beam/pull/5971#issuecomment-406074873
The race condition is fixed in https://github.com/apache/beam/pull/5975
The root cause was that we were simply sending the requests for put artifact
and completing it on client without waiting for the completion from the server.
My understanding was that gRPC would make sure that onComplete waits for
completion from the server as well, which is not the case.
