Saisai Shao commented on SPARK-19688:
-------------------------------------
According to my test, "spark.yarn.credentials.file" will be overwritten in
yarn-client to point to a correct path when launching application
(https://github.com/apache/spark/blob/master/resource-managers/yarn/src/main/scala/org/apache/spark/deploy/yarn/Client.scala#L737).
So even Spark Streaming checkpoint still keeps the old configuration, it will
be overwritten when the new application is started. So I don't see an issue
here except this weird setting.
