Nishan Shetty created MAPREDUCE-4460:
----------------------------------------
Summary: Refresh queue throws IO exception after configuring wrong
queue capacity
Key: MAPREDUCE-4460
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4460
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Affects Versions: 2.1.0-alpha
Reporter: Nishan Shetty
Scenario:
1.My setup has a,b queues(each with capacity say 50%) under root queue
2.Start the process
3.Add one more queue 'c' under root
4.Configure some capacity for 'c' such that total capacity of a,b,c is not
equal to 100
5.Now do refresh queues, it will throw exception as wrong capacity(This is
expected as capacity was not equal to 100).
6.Now reconfigure queue capacities of a,b,c such that total capacity is 100
5.Now do refresh queues again
Observed that it throws IO exception
