Any objections or comments from Spark 2 users on this topic? — Alexey

In two words, it brings some burden to Spark runner support that we would like to avoid in the future. From the devs perspective I don’t see any objections about this. So, I’d like to know if there are users that still uses Spark2 for their Beam pipelines and it will be critical for them to keep using it. Please, share any your opinion on this! — Alexey [1] https://lists.apache.org/thread/opfhg3xjb9nptv878sygwj9gjx38rmco > On 31 Mar 2022, at 17:51, Alexey Romanenko <aromanenko....@gmail.com> wrote: > > Hi everyone, > > For the moment, Beam Spark Runner supports two versions of Spark - 2.x and > 3.x. > > Taking into account the several things that: > - almost all cloud providers already mostly moved to Spark 3.x as a main > supported version; > - the latest Spark 2.x release (Spark 2.4.8, maintenance release) was done > almost a year ago; > - Spark 3 is considered as a mainstream Spark version for development and bug > fixing; > - better to avoid the burden of maintenance (there are some incompatibilities > between Spark 2 and 3) of two versions; > > I’d suggest to stop support Spark 2 for the Spark Runner in the one of the > next Beam releases. > > What are your thoughts on this?
