-----------------------------------
Summary: spark ec2 script enters infinite loop when run-instance
fails
Key: SPARK-6900
URL: https://issues.apache.org/jira/browse/SPARK-6900
Project: Spark
Issue Type: Bug
Components: EC2
Affects Versions: 1.3.0
Reporter: Guodong Wang
I am using spark-ec2 scripts to launch spark cluters in AWS.
Recently, in our AWS region, there were some tech issues about AWS EC2
service.
When spark-ec2 send the run-instance requests to EC2, not all the requested
instances were launched. Some instance was terminated by AWS-EC2 service
before it was up.
But spark-ec2 script would wait for all the instances to enter 'ssh-ready'
status. So, the script enters the infinite loop. Because the terminated
instances would never be 'ssh-ready'.
In my opinion, it should be OK if some of the slave instances were terminated.
As long as the master node is running, the terminated slaves should be filtered
and the cluster should be setup.
