Hi all, A heads up in case others hit this and are confused… This nice addition <https://github.com/apache/spark/pull/612> causes an error if running the spark-ec2.py deploy script from a version other than master (e.g. 0.8.0).
The error occurs during launch, here: ... Creating local config files... configuring /etc/ganglia/gmond.conf Traceback (most recent call last): File "./deploy_templates.py", line 89, in <module> text = text.replace("{{" + key + "}}", template_vars[key]) TypeError: expected a character buffer object Deploying Spark config files... chmod: cannot access `/root/spark/conf/spark-env.sh': No such file or directory ... And then several more errors because of missing variables (though the cluster itself launches, there are several configuration problems, e.g. with HDFS). deploy_templates fails because the new SPARK_MASTER_OPTS and SPARK_WORKER_INSTANCES don't exist, and earlier versions of spark-ec2.py still use deploy_templates from https://github.com/mesos/spark-ec2.git -b v2, which has the new variables. Using the updated spark-ec2.py from master works fine. -- Jeremy --------------------- Jeremy Freeman, PhD Neuroscientist @thefreemanlab -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/spark-ec2-error-tp5323.html Sent from the Apache Spark User List mailing list archive at Nabble.com.
