> Key: SPARK-35365
> URL: https://issues.apache.org/jira/browse/SPARK-35365
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.1.1
> Reporter: yao
> Priority: Major
>
> I have a big sql with a few width tables join and complex logic, when I run
> that in spark 2.4 , it will take 20 minues in analyze phase, when I use spark
> 3.1.1, it will use about 40 minutes,
> I need set spark.sql.analyzer.maxIterations=1000 in spark3.1.1.
> or spark.sql.optimizer.maxIterations=1000 in spark2.4.
> no other special setting for this .
> I check on the spark ui , I find that there is no job generated, all executor
> have no active tasks, and when I set log level to debug, I find that the job
> is in analyze phase, analyze the fields reference.
> this phase use too long time.
