Michael Armbrust created SPARK-1726:
---------------------------------------

             Summary: Tasks that fail to serialize remain in active stages forever.
                 Key: SPARK-1726
                 URL: https://issues.apache.org/jira/browse/SPARK-1726
             Project: Spark
          Issue Type: Bug
          Components: Web UI
            Reporter: Michael Armbrust


In the spark shell.
{code}
scala> class Adder(x: Int) { def apply(a: Int) = a + x }
defined class Adder
scala> val add = new Adder(10)
scala> sc.parallelize(1 to 10).map(add(_)).collect()
{code}

You get:
{code}

However, the web ui is messed up.  See attached screen shot.
