I've found a workaround. I set up an http server serving the jar, and pointed to the http url in spark submit. Which brings me to ask.... would it be a good option to allow spark-submit to upload a local jar to the master, which the master can then serve via an http interface? The master already runs a web UI, so I imagine we could allow it to receive jars, and serve them as well. Perhaps an additional flag could be used to signify that the local jar should be uploaded in this manner? I'd be happy to take a stab at it...but thoughts? -Ashic.

The S3 bucket does have access restrictions, but the instances in which the Spark master and workers run have an IAM role policy that allows them access to it. As such, we don't really configure the cli with credentials...the IAM roles take care of that. Is there a way to make Spark work the same way? Or should I get temporary credentials somehow (like http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_use-resources.html ), and use them to somehow submit the job? I guess I'll have to set it via environment variables; I can't put it in application code, as the issue is in downloading the jar from S3. -Ashic.

Is your s3 bucket without any access restrictions? Best regards / Mit freundlichen Grüßen / Sincères salutations M.

I can submit jobs using "--deploy-mode client", however using "--deploy-mode cluster" is proving to be a challenge. I've tries this: spark-submit --class foo --master spark:://master-ip:7077 --deploy-mode cluster s3://bucket/dir/foo.jar When I do this, I get: 16/07/01 16:23:16 ERROR ClientEndpoint: Exception from cluster was: java.lang.IllegalArgumentException: AWS Access Key ID and Secret Access Key must be specified as the username or password (respectively) of a s3 URL, or by setting the fs.s3.awsAccessKeyId or fs.s3.awsSecretAccessKey properties (respectively). java.lang.IllegalArgumentException: AWS Access Key ID and Secret Access Key must be specified as the username or password (respectively) of a s3 URL, or by setting the fs.s3.awsAccessKeyId or fs.s3.awsSecretAccessKey properties (respectively). at org.apache.hadoop.fs.s3.S3Credentials.initialize(S3Credentials.java:66) at org.apache.hadoop.fs.s3.Jets3tFileSystemStore.initialize(Jets3tFileSystemStore.java:82) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.apache.hadoop.io.retry.RetryInvocationHandler.invokeMethod(RetryInvocationHandler.java:85) at org.apache.hadoop.io.retry.RetryInvocationHandler.invoke(RetryInvocationHandler.java:62) Now I'm not using any S3 or hadoop stuff within my code (it's just an sc.parallelize(1 to 100)). So, I imagine it's the driver trying to fetch the jar. I haven't set the AWS Access Key Id and Secret as mentioned, but the role the machine's are in allow them to copy the jar. In other words, this works: aws s3 cp s3://bucket/dir/foo.jar /tmp/foo.jar I'm using Spark 1.6.2, and can't really think of what I can do so that I can submit the jar from s3 using cluster deploy mode. I've also tried simply downloading the jar onto a node, and spark-submitting that... that works in client mode, but I get a not found error when using cluster mode. Any help will be appreciated.
