Class QueueCapacityConfigParser

java.lang.Object

org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.conf.QueueCapacityConfigParser

public class QueueCapacityConfigParser
extends java.lang.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.
