Karthik Kambatla commented on MAPREDUCE-4311: --------------------------------------------- The fix seems fairly straightforward - modify the capacities from int to float. The classes that call getCapacity() eventually convert it to a float value, anyway. I ll upload a patch with the changes later today. > Capacity scheduler.xml does not accept decimal values for capacity and > maximum-capacity settings > ------------------------------------------------------------------------------------------------ > > Key: MAPREDUCE-4311 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-4311 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: contrib/capacity-sched, mrv2 > Affects Versions: 0.23.3 > Reporter: Thomas Graves > Assignee: Karthik Kambatla > > if capacity scheduler capacity or max capacity set with decimal it errors: > - Error starting ResourceManager > java.lang.NumberFormatException: For input string: "10.5" > at > java.lang.NumberFormatException.forInputString(NumberFormatException.java:48) > at java.lang.Integer.parseInt(Integer.java:458) > at java.lang.Integer.parseInt(Integer.java:499) > at org.apache.hadoop.conf.Configuration.getInt(Configuration.java:713) > at > org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacitySchedulerConfiguration.getCapacity(CapacitySchedulerConfiguration.java:147) > at > org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.LeafQueue.<init>(LeafQueue.java:147) > at > org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler.parseQueue(CapacityScheduler.java:297) > at > 0.20 used to take decimal and this could be an issue on large clusters that > would have queues with small allocations. -- This message is automatically generated by JIRA.
