[SPARK-23559][SS] Add epoch ID to DataWriterFactory. ## What changes were proposed in this pull request? Add an epoch ID argument to DataWriterFactory for use in streaming. As detailed in the JIRA, this is required to support a consistent lifecycle. I considered making a separate streaming interface and adding the epoch ID only to that one, but I think it requires a lot of extra work for no real gain. I think it makes sense to define epoch 0 as the one and only epoch of a non-streaming query. ## How was this patch tested? existing unit tests You can merge this pull request into a Git repository by running: $ git pull https://github.com/jose-torres/spark api2 Alternatively you can review and apply these changes as the patch at: https://github.com/apache/spark/pull/20710.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #20710 ---- commit 3b21dd0e6413326267386d38e06855a5914958a4 Author: Jose Torres <jose@...> Date: 2018-02-21T18:52:45Z change api commit c5f0de035dd8fd540099fc05740df4e09c1048e4 Author: Jose Torres <jose@...> Date: 2018-02-21T23:00:30Z add docs commit ad5523d6dadcef29730e3ebca352d0832fa33b65 Author: Jose Torres <jose@...> Date: 2018-02-22T19:56:44Z don't use epochId in batch sources commit 5bbd497214ef63b55df000cd56912121f090526e Author: Jose Torres <jose@...> Date: 2018-02-22T21:18:41Z change comment ---- --- --------------------------------------------------------------------- To unsubscribe, e-mail: reviews-unsubscr...@spark.apache.org For additional commands, e-mail: reviews-h...@spark.apache.org
