Subject [jira] [Assigned] (SPARK-19482) Fail it if 'spark.master' is set with different value
Date Tue, 07 Feb 2017 03:29:41 GMT


Apache Spark reassigned SPARK-19482:

    Assignee: Apache Spark

> Fail it if 'spark.master' is set with different value
> -----------------------------------------------------
>                 Key: SPARK-19482
>                 URL:
>             Project: Spark
>          Issue Type: Improvement
>          Components: Spark Core
>    Affects Versions: 2.0.2, 2.1.0
>            Reporter: Genmao Yu
>            Assignee: Apache Spark
> First, there is no need to set 'spark.master' multi-times with different values. Second,
It is possible for users to set the different 'spark.master' in code with
> `spark-submit` command, and will confuse users. So, we should do once check if the 'spark.master'
already exists in settings and if the previous value is the same with current value. Throw
a IllegalArgumentException when previous value is different with current value.
