Cheng Lian 27e71a2cd9 [SPARK-14244][SQL] Don't use SizeBasedWindowFunction.n created on executor side when evaluating window functions ... ## What changes were proposed in this pull request? `SizeBasedWindowFunction.n` is a global singleton attribute created for evaluating size based aggregate window functions like `CUME_DIST`. However, this attribute gets different expression IDs when created on both driver side and executor side. This PR adds `withPartitionSize` method to `SizeBasedWindowFunction` so that we can easily rewrite `SizeBasedWindowFunction.n` on executor side. ## How was this patch tested? A test case is added in `HiveSparkSubmitSuite`, which supports launching multi-process clusters.
