[jira] [Updated] (SPARK-18142) Spark Master tries to launch workers
145 times within 1 minute

Burak Yavuz updated SPARK-18142:
--------------------------------
Component/s: Spark Core
> Spark Master tries to launch workers 145 times within 1 minute
> --------------------------------------------------------------
>
> Key: SPARK-18142
> URL: https://issues.apache.org/jira/browse/SPARK-18142
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.0.1
> Reporter: Burak Yavuz
>
> I observed a case where an instance running a worker was killed. The Spark Master tried to launch new executors at that instance, even though the instance didn't exist anymore and failed 145 times within 1 minute, and then killed the application.
> The instance takes ~10 minutes to be replaced. The master should at least have an exponential backoff mechanism when performing these retries so that it gives the infrastructure time to recover.
