Subject CDH5 Spark on EC2
Date Wed, 02 Apr 2014 07:44:17 GMT
I’ve been able to get CDH5 up and running on EC2 and according to Cloudera Manager, Spark
is running healthy.

But when I try to run spark-shell, I eventually get the error:

14/04/02 07:18:18 INFO client.AppClient$ClientActor: Connecting to master spark://ip-172-xxx-xxx-xxx:7077...
14/04/02 07:18:38 ERROR client.AppClient$ClientActor: All masters are unresponsive! Giving
14/04/02 07:18:38 ERROR cluster.SparkDeploySchedulerBackend: Spark cluster looks dead, giving
14/04/02 07:18:38 ERROR scheduler.TaskSchedulerImpl: Exiting due to error from cluster scheduler:
Spark cluster looks down

Wondering which configurations I would need to change to get this to work?
