Spark支持倾斜提示吗?

我面临一些数据倾斜问题,我想看看Spark提示是否能帮我。但是,我不确定是否支持倾斜提示。这些网站: https://docs.databricks.com/spark/latest/spark-sql/skew-join.html#relation-columns-and-skew-values Spark Scala equivalent for SKEW join hints

然而, https://jaceklaskowski.gitbooks.io/mastering-spark-sql/spark-sql-hint-framework.html#spark-analyzer 声称 Spark SQL supports COALESCE and REPARTITION and BROADCAST hints. All remaining unresolved hints are silently removed from a query plan at analysis.

哪一个是正确的?我正在运行Spark 2.2
