[jira] [Created] (MAPREDUCE-6916) History server scheduling tasks at fixed rate can be problematic when those tasks are slow

2017-07-18 Thread Jason Lowe (JIRA)
Jason Lowe created MAPREDUCE-6916:
-

 Summary: History server scheduling tasks at fixed rate can be 
problematic when those tasks are slow
 Key: MAPREDUCE-6916
 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6916
 Project: Hadoop Map/Reduce
  Issue Type: Bug
  Components: jobhistoryserver
Affects Versions: 2.7.4
Reporter: Jason Lowe


The job history server currently schedules both the task of moving jobs from 
intermediate to done and the task of cleaning jobs at a fixed rate.  If those 
tasks take longer than the rate period to execute then a backlog of 
to-be-scheduled tasks can build up and cause a long storm of them to execute 
later when the blockage clears.
