----------------------------------
Summary: Coalesce partiton assert error after skew join
optimization
Key: SPARK-46590
URL: https://issues.apache.org/jira/browse/SPARK-46590
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 3.3.4, 3.5.0, 3.4.1, 3.4.0, 3.3.2, 3.3.3, 3.3.1, 4.0.0,
3.5.1
Reporter: Jackey Lee
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.
