of too much Task
[ https://issues.apache.org/jira/browse/SPARK-29424?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sean R. Owen resolved SPARK-29424.
----------------------------------
Resolution: Won't Fix
> Prevent Spark to committing stage of too much Task
> --------------------------------------------------
>
> Key: SPARK-29424
> URL: https://issues.apache.org/jira/browse/SPARK-29424
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 2.4.0, 3.0.0
> Reporter: angerszhu
> Priority: Major
>
> Our user always submit bad SQL in query platform, Such as :
> # write wrong join condition but submit that sql
> # write wrong where condition
> # etc..
> This case will make Spark scheduler to submit a lot of task. It will cause spark run very slow and impact other user(spark thrift server) even run out of memory because of too many object generated by a big num of tasks.
> So I add a constraint when submit tasks and abort stage early when TaskSet size num is bigger then set limit . I wonder if the community will accept this way.
