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

             Summary: JobProgressListener should limit memory usage of tasks in stages.
                 Key: SPARK-15083
                 URL: https://issues.apache.org/jira/browse/SPARK-15083
             Project: Spark
          Issue Type: Bug
          Components: Web UI
    Affects Versions: 1.6.0, 1.5.2, 2.0.0
            Reporter: Zheng Tan


History Server will load all tasks in a stage, which would cause memory leak if tasks occupy
too many memory. 

In the following example, a single application would consume 1.1G memory of History Sever.


I think we should limit tasks memory usages by adding spark.ui.retainedTasks.
