Subject [jira] [Resolved] (SPARK-29424) Prevent Spark to committing stage of too much Task
Date Sat, 26 Oct 2019 21:01:00 GMT


Sean R. Owen resolved SPARK-29424.
    Resolution: Won't Fix

> Prevent Spark to committing stage of too much Task
> --------------------------------------------------
>                 Key: SPARK-29424
>                 URL:
>             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.
