      Description

      JobTracker is vulnerable to memory errors/attacks. Few of them are as follows

      • JOB INIT : lot of users submitting large jobs. As every jobs is expanded, the jobtracker's memory can be completely used up
      • JSP : jsp (jobhistory.jsp etc) can also interfere with jobtracker's memory and hence the jobtracker should be protected against such attacks
      • OLD JOBS : lot of completed jobs can garble up jobtracker's memory and hence should be periodically cleaned up. HADOOP-4766 addresses this.

      The main intention of this issue is to track various jira's that help jobtracker battle memory attacks. Jobtracker should always be up and available.
