The following commit(s) were added to refs/heads/branch-2.4 by this push: new 77006b2 [SPARK-32073][R] Drop R < 3.5 support 77006b2 is described below commit 77006b2c65e0e4b6b9facddbb13aa88a264adbe2 Author: HyukjinKwon <gurwls...@apache.org> AuthorDate: Wed Jun 24 11:05:27 2020 +0900 [SPARK-32073][R] Drop R < 3.5 support Spark 3.0 accidentally dropped R < 3.5. It is built by R 3.6.3 which not support R < 3.5: ``` Error in readRDS(pfile) : cannot read workspace version 3 written by R 3.6.3; need R 3.5.0 or newer version. ``` In fact, with SPARK-31918, we will have to drop R < 3.5 entirely to support R 4.0.0. This is inevitable to release on CRAN because they require to make the tests pass with the latest R. To show the supported versions correctly, and support R 4.0.0 to unblock the releases. In fact, no because Spark 3.0.0 already does not work with R < 3.5. Compared to Spark 2.4, yes. R < 3.5 would not work. Jenkins should test it out. Closes #28908 from HyukjinKwon/SPARK-32073.
