Hi, All.
What about providing a official benchmark result between `Apache Spark on
JDK7` and `Apache Spark on JDK8`?
I think that is enough for this issue since we cannot drive users.
We had better let users choose one of JDK7/JDK8 for their own benefits.
Bests,
Dongjoon.

Sure, signalling well ahead of time is good, as is getting better
performance from Java 8; but do either of those interests really require
dropping Java 7 support sooner rather than later?
Now, to retroactively copy edit myself, when I previously wrote "after all
or nearly all relevant clusters
i care about signalling it in advance mostly. and given the performance
differences we do have some interest in pushing towards java 8

dropping java 7 support was considered for spark 2.0.x but we decided
against it.
ideally dropping support for a java version should be communicated far in
advance to facilitate the transition.
is this the right time to make that decision and start communicating it
(mailing list, jira, etc.)?
Ok cool, i didn't vote as I've done no real testing myself and i think the
window had already closed anyway.
I'm happy to wait for 2.0.1 for our systems.
Thanks,

I will document this as a known issue in the release notes. We have other
bugs that we have fixed since RC5, and we can fix those together in 2.0.1.
