Every thing you choose to support generates a maintenance burden. Support 3 versions of Scala would be a huge maintenance burden, for example, as is supporting 2 versions of the JDK. Just note that, technically, we do support 2 versions of the jdk today; we just don't do a lot of automated testing on jdk 8 (PRs are all built with jdk 7 AFAIK). So at the end it's a compromise. How many users will be affected by your choices? That's the question that I think is the most important. If switching to java 8-only means a bunch of users won't be able to upgrade, it means that Spark 2.0 will get less use than 1.x and will take longer to gain traction. That has other ramifications - such as less use means less issues might be found and the overall quality may suffer in the beginning of this transition. -- Marcelo --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@spark.apache.org For additional commands, e-mail: dev-h...@spark.apache.org
