[jira] Created: (MAPREDUCE-1109) ConcurrentModificationException in
jobtracker.jsp
ConcurrentModificationException in jobtracker.jsp
-------------------------------------------------
Key: MAPREDUCE-1109
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1109
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: jobtracker
Affects Versions: 0.20.1
Reporter: dhruba borthakur
Assignee: dhruba borthakur
The jobtracker.jsp invoked methods tracker.runningJobs(), tracker.completedJobs() and tracker.failedJobs() but these methods are not synchronized and can cause ConcurrentModificationException if the JT is concurrently changing the contents of these datastructures.

Chris Douglas reopened MAPREDUCE-1109:
--------------------------------------
This still exists in 0.20, right? Sorry, I only mentioned MAPREDUCE-679 because this was fixed as a detour in that issue and the fix should either be backported or changed to match whatever approach is agreed on here.
