      Description

      When the node health check script takes more than "mapred.healthChecker.script.timeout" to return, it should display a timeout message. Instead it displays the full stacktrace as below:

      java.io.IOException: Stream closed at java.io.BufferedInputStream.getBufIfOpen(BufferedInputStream.java:145)

      at java.util.TimerThread.run(Timer.java:462) 
      

      Also the "mapred.healthChecker.script.timeout" is not being reflected in the job.xml. It always picks up the default value. It is just an UI issue.
