> Key: KUDU-2254
> URL: https://issues.apache.org/jira/browse/KUDU-2254
> Project: Kudu
> Issue Type: Improvement
> Components: spark
> Affects Versions: 1.5.0
> Reporter: Hao Hao
>
> 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.
