------------------------------------------
Summary: 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.
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)
fairscheduler-invalid-data.xml file :
<allocations>
<pool name="production">
<schedulingMode>FIFO</schedulingMode>
<weight>invalid_weight</weight>
<minShare>2</minShare>
</pool>
</allocations>
Stacktrace :
Exception in thread "main" java.lang.NumberFormatException: For input string:
"invalid_weight"
