…eExecutionEnabled ### What changes were proposed in this pull request? This PR makes `repartition`/`DISTRIBUTE BY` obeys [initialPartitionNum](https://github.com/apache/spark/blob/af4248b2d661d04fec89b37857a47713246d9465/sql/catalyst/src/main/scala/org/apache/spark/sql/internal/SQLConf.scala#L446-L455) when adaptive execution enabled. ### Why are the changes needed? To make `DISTRIBUTE BY`/`GROUP BY` partitioned by same partition number. How to reproduce: ```scala spark.sql("CREATE TABLE spark_31220(id int)") spark.sql("set spark.sql.adaptive.enabled=true") spark.sql("set spark.sql.adaptive.coalescePartitions.initialPartitionNum=1000") ``` Before this PR: ``` scala> spark.sql("SELECT id from spark_31220 GROUP BY id").explain == Physical Plan == AdaptiveSparkPlan(isFinalPlan=false) +- HashAggregate(keys=[id#5], functions=[]) +- Exchange hashpartitioning(id#5, 1000), true, [id=palantir#171] +- HashAggregate(keys=[id#5], functions=[]) +- FileScan parquet default.spark_31220[id#5] scala> spark.sql("SELECT id from spark_31220 DISTRIBUTE BY id").explain == Physical Plan == AdaptiveSparkPlan(isFinalPlan=false) +- Exchange hashpartitioning(id#5, 200), false, [id=palantir#179] +- FileScan parquet default.spark_31220[id#5] ``` After this PR: ``` scala> spark.sql("SELECT id from spark_31220 GROUP BY id").explain == Physical Plan == AdaptiveSparkPlan(isFinalPlan=false) +- HashAggregate(keys=[id#5], functions=[]) +- Exchange hashpartitioning(id#5, 1000), true, [id=palantir#171] +- HashAggregate(keys=[id#5], functions=[]) +- FileScan parquet default.spark_31220[id#5] scala> spark.sql("SELECT id from spark_31220 DISTRIBUTE BY id").explain == Physical Plan == AdaptiveSparkPlan(isFinalPlan=false) +- Exchange hashpartitioning(id#5, 1000), false, [id=palantir#179] +- FileScan parquet default.spark_31220[id#5] ``` ### Does this PR introduce any user-facing change? No. ### How was this patch tested? Unit test. Closes apache#27986 from wangyum/SPARK-31220.
