Class QueueCapacityConfigParser

java.lang.Object
org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.conf.QueueCapacityConfigParser
public class QueueCapacityConfigParser extends Object
A class that parses QueueCapacityVector from the capacity configuration property set for a queue. A new syntax for capacity property could be implemented, by creating a parser with a regex to match the pattern and a method that creates a QueueCapacityVector from the matched pattern. Extending the parsers field with a Parser object in the constructor is needed in this case. A new capacity type for the existing parsers could be added by extending the QueueCapacityVector.QueueCapacityType with a new type and its associated postfix symbol.
