> Recently when we were testing TPCDS Q71, we found that if `spark.sql.shuffle.partitions` and `spark.sql.adaptive.coalescePartitions.initialPartitionNum` are both set to the number of executor cores, an AssertError may be reported in coalescePartition due to the partitionSpecs of joins after skew are different.
