             Summary: Spark worker throw Exception when uber jar's http url contains query string
                 Key: SPARK-17855
                 URL: https://issues.apache.org/jira/browse/SPARK-17855
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
            Reporter: Hao Ren
            Priority: Minor


spark-submit support jar url with http protocol

If the url contains any query strings, *worker.DriverRunner.downloadUserJar * method will throw "Did not see expected jar" exception. This is because this method checks the existance of a downloaded jar whose name contains query strings.

This is a problem when your jar is located on some web service which requires some additional information to retrieve the file. For example, to download a jar from s3 bucket via http, the url contains signature, datetime, etc as query string.

{code}
https://s3.amazonaws.com/deploy/spark-job.jar
?X-Amz-Algorithm=AWS4-HMAC-SHA256
&X-Amz-Credential=<your-access-key-id>/20130721/us-east-1/s3/aws4_request
&X-Amz-Date=20130721T201207Z
&X-Amz-Expires=86400
&X-Amz-SignedHeaders=host
&X-Amz-Signature=<signature-value>  
{code}

Woker will look for a jar named

"spark-job.jar?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=<your-access-key-id>/20130721/us-east-1/s3/aws4_request&X-Amz-Date=20130721T201207Z&X-Amz-Expires=86400&X-Amz-SignedHeaders=host&X-Amz-Signature=<signature-value>"

instead of

"spark-job.jar"

Hence, all the query string should be removed before checking jar existance.
