      Description

      If a Spark job's job description contains a single quote (') then the driver UI's job event timeline will fail to render due to Javascript errors. To reproduce these symptoms, run

      sc.setJobDescription("double quote: \" ")
      sc.parallelize(1 to 10).count()
      
      sc.setJobDescription("single quote: ' ")
      sc.parallelize(1 to 10).count() 
      

      and browse to the driver UI. This will currently result in an "Uncaught SyntaxError" because the single quote is not escaped and ends up closing a Javascript string literal too early.

      I think that a simple fix may be to change the relevant JS to use double quotes and then to use the existing XML escaping logic to escape the string's contents.
