> Since KuduContext carries a bunch of information for client connection, such as authentication token, KuduContext should be created in the driver and shared with executors.
> Even if we have put comments for KuduContext class (https://github.com/apache/kudu/blob/master/java/kudu-spark/src/main/scala/org/apache/kudu/spark/kudu/KuduContext.scala#L43), it would be great to provide a way to warn users (e.g Logging) about such behavior since this kind of issues are very subtle to detect.
