The > cluster Total Memory can either decrease or increase. We had a cluster where > total memory decreased to almost 1/6th the capacity. Running on a small test > cluster resulted in the capacity going up by simply adding a queue and > running wordcount. > Looking at the RM logs, used memory can go negative but other logs show the > number positive: > 2012-10-21 22:56:44,796 [ResourceManager Event Processor] INFO > org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.ParentQueue: > assignedContainer queue=root usedCapacity=0.0375 absoluteUsedCapacity=0.0375 > used=memory: 7680 cluster=memory: 204800 > 2012-10-21 22:56:45,831 [ResourceManager Event Processor] INFO > org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.ParentQueue: > completedContainer queue=root usedCapacity=-0.0225 > absoluteUsedCapacity=-0.0225 used=memory: -4608 cluster=memory: 204800 > -- This message is automatically generated by JIRA.
