> We have spark.shuffle.io.connectionTimeout for timeout checking when shuffle clients establish connections with shuffle servers. We also use it to check the established connection is idled or dead too. If we want a connection that can keep alive for a long time, we may increase the blocking time to create a shuffle client if the server is busy at that time.
> In practice, we always use connection timeout and session timeout to control these two different phases.
