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.
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.
