Shixiong Zhu commented on SPARK-18142:
--------------------------------------
Looks like we need a blacklist mechanism for workers.
> 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.
