Read input file from jar while running application from spark-submit

I have an input file that is custom delimited and is passed to newAPIHadoopFile to convert as RDD[String]. The file resides under the project resource directory. The following code works well when run from the Eclipse IDE.

  val path = this.getClass()
                 .getClassLoader()
                 .getResource(fileName)                   
                 .toURI().toString()
  val conf = new org.apache.hadoop.conf.Configuration() 
  conf.set("textinputformat.record.delimiter", recordDelimiter)

  return sc.newAPIHadoopFile(
      path,
      classOf[org.apache.hadoop.mapreduce.lib.input.TextInputFormat],
      classOf[org.apache.hadoop.io.LongWritable], 
      classOf[org.apache.hadoop.io.Text], 
      conf)
    .map(_._2.toString) 

However when I run it on spark-submit (with a uber jar) as follows

   spark-submit /Users/anon/Documents/myUber.jar

I get the below error.

 Exception in thread "main" java.lang.IllegalArgumentException: java.net.URISyntaxException: Relative path in absolute URI: jar:file:/Users/anon/Documents/myUber.jar!/myhome-data.json

Any inputs please?
