Bharat Venkat created SPARK-7386:
------------------------------------
Summary: Spark application level metrics
application.$AppName.$number.cores doesn't reset on Standalone Master deployment
Key: SPARK-7386
URL: https://issues.apache.org/jira/browse/SPARK-7386
Project: Spark
Issue Type: Bug
Affects Versions: 1.3.0
Reporter: Bharat Venkat
Spark publishes a metric called application.$AppName.$number.cores that gets
published which monitors number of cores assigned to an application. However
there is a bug as of 1.3 standalone deployment, where this metric doesn't go
down to 0 after the application ends.
It looks like standalone master holds onto the old state and continues to
publish a stale metric.
