-----------------------------------
Summary: 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
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.
