Laurent Goujon commented on DRILL-5311:
---------------------------------------
you're correct, I forgot that run is a blocking operation. But I guess in that
case, there's no check about the actual completion of the handshake, and
SUCCESS is always returned.
> C++ connector connect doesn't wait for handshake to complete

> Key: DRILL-5311
> URL: https://issues.apache.org/jira/browse/DRILL-5311
> Project: Apache Drill
> Issue Type: Bug
> Components: Client - C++
> Reporter: Laurent Goujon
>
> The C++ connector connect methods returns okay as soon as the tcp connection
> is succesfully established between client and server, and the handshake
> message is sent. However it doesn't wait for handshake to have completed.
> The consequence is that if handshake failed, the error is deferred to the
> first query, which might be unexpected by the application.
> I believe that validateHanshake method in drillClientImpl should wait for the
> handshake to complete, as it seems a bit more saner...
