Github user ueshin commented on the pull request: https://github.com/apache/spark/pull/2638#issuecomment-57800537 @srowen, Thank you for your comment. Indeed, when deploy completed apps to Spark cluster, there is a particular instance of Spark. But Spark app developers will use artifacts in Maven Central while developing and unit-testing. The artifacts seem to be built for Hadoop 2, so if they want to test with Hadoop 1, it won't work. What do you think?
