Apache Spark reassigned SPARK-17663:
------------------------------------
Assignee: (was: Apache Spark)
> SchedulableBuilder should handle invalid data access via
> scheduler.allocation.file
> ----------------------------------------------------------------------------------
>
> Key: SPARK-17663
> URL: https://issues.apache.org/jira/browse/SPARK-17663
> Project: Spark
> Issue Type: Bug
> Components: Scheduler
> Affects Versions: 2.0.1
> Reporter: Eren Avsarogullari
>
> If spark.scheduler.allocation.file has invalid *minShare* or/and *weight*,
> they cause NumberFormatException due to function *toInt* and SparkContext can
> not be initialized. Currently, if schedulingMode does not have valid value, a
> warning message is logged and default value is set as FIFO. Same pattern can
> be used for minShare(default: 0) and weight(default: 1) as well.
> *Code to Reproduce* :
> {code}
> val conf = new
> SparkConf().setAppName("spark-fairscheduler").setMaster("local")
> conf.set("spark.scheduler.mode", "FAIR")
> conf.set("spark.scheduler.allocation.file",
> "src/main/resources/fairscheduler-invalid-data.xml")
> val sc = new SparkContext(conf)
> {code}
> *fairscheduler-invalid-data.xml* :
> {code}
> <allocations>
> <pool name="production">
> <schedulingMode>FIFO</schedulingMode>
> <weight>invalid_weight</weight>
> <minShare>2</minShare>
> </pool>
> </allocations>
> {code}
> *Stacktrace* :
> {code}
> Exception in thread "main" java.lang.NumberFormatException: For input string:
> "invalid_weight"
