Hi guys,
To illustrate the current discussion about Spark versions support, you can take
a look on:
--
Spark 1 & Spark 2 Support Branch
https://github.com/jbonofre/beam/tree/BEAM-1920-SPARK2-MODULES
This branch contains a Spark runner common module compatible with both Spark 1.x
and 2.x. For convenience, we introduced spark1 & spark2 modules/artifacts
containing just a pom.xml to define the dependencies set.
--
Spark 2 Only Branch
https://github.com/jbonofre/beam/tree/BEAM-1920-SPARK2-ONLY
This branch is an upgrade to Spark 2.x and "drop" support of Spark 1.x.
As I'm ready to merge one of the other in the PR, I would like to complete the
vote/discussion pretty soon.
Correct me if I'm wrong, but it seems that the preference is to drop Spark 1.x
to focus only on Spark 2.x (for the Spark 2 Only Branch).
I would like to call a final vote to act the merge I will do:
[ ] Use Spark 1 & Spark 2 Support Branch
[ ] Use Spark 2 Only Branch
This informal vote is open for 48 hours.
Please, let me know what your preference is.
Thanks !
Regards
JB

Hi Beamers,
I'm forwarding this discussion & vote from the dev mailing list to the user
mailing list.
The goal is to have your feedback as user.
Basically, we have two options:
1. Right now, in the PR, we support both Spark 1.x and 2.x using three artifacts
(common, spark1, spark2). You, as users, pick up spark1 or spark2 in your
dependencies set depending the Spark target version you want.
2. The other option is to upgrade and focus on Spark 2.x in Beam 2.3.0. If you
still want to use Spark 1.x, then, you will be stuck up to Beam 2.2.0.
Thoughts ?
Thanks !

JB

Subject: [VOTE] Drop Spark 1.x support to focus on Spark 2.x

Hi all,
as you might know, we are working on Spark 2.x support in the Spark runner.
I'm working on a PR about that:
https://github.com/apache/beam/pull/3808
Today, we have something working with both Spark 1.x and 2.x from a code
standpoint, but I have to deal with dependencies. It's the first step of the
update as I'm still using RDD, the second step would be to support dataframe
(but for that, I would need PCollection elements with schemas, that's another
topic on which Eugene, Reuven and I are discussing).
However, as all major distributions now ship Spark 2.x, I don't think it's
required anymore to support Spark 1.x.
If we agree, I will update and cleanup the PR to only support and focus on Spark
2.x.
So, that's why I'm calling for a vote:
[ ] +1 to drop Spark 1.x support and upgrade to Spark 2.x only
[ ] 0 (I don't care ;))
[ ] -1, I would like to still support Spark 1.x, and so having support of
both Spark 1.x and 2.x (please provide specific comment)
This vote is open for 48 hours (I have the commits ready, just waiting the end
of the vote to push on the PR).
Thanks !
Regards
JB
