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.

They don't require dropping it sooner rather than later. But signalling in
some way that java 8 is (strongly) recommend would be good.

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

i care about signalling it in advance mostly. and given the performance
differences we do have some interest in pushing towards java 8

Why the push to remove Java 7 support as soon as possible (which is how I
read your "cluster admins plan to migrate by date X, so Spark should end
Java 7 support then, too")? First, I don't think we should be removing
Java 7 support until some time after all or nearly all relevant clusters
are act
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.)? per
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,
