------------------------------------

             Summary: Dynamically add jar into Spark Driver's classpath.
                 Key: SPARK-5377
                 URL: https://issues.apache.org/jira/browse/SPARK-5377
             Project: Spark
          Issue Type: Improvement
    Affects Versions: 1.2.0
            Reporter: Chengxiang Li


Spark support dynamically add jar to executor classpath through SparkContext::addJar(), while it does not support dynamically add jar into driver classpath. In most case(if not all the case), user dynamically add jar with SparkContext::addJar()  because some classes from the jar would be referred in upcoming Spark job, which means the classes need to be loaded in Spark driver side either,e.g during serialization. I think it make sense to add an API to add jar into driver classpath, or just make it available in SparkContext::addJar(). HIVE-9410 is a real case from Hive on Spark.
