All Implemented Interfaces:

org.apache.hadoop.conf.Configurable, org.apache.hadoop.util.Tool

public class HerdJsv
extends org.apache.hadoop.conf.Configured
implements org.apache.hadoop.util.Tool

The HerdJsv class is a JSV that translates hard resource requests for the hdfs_input resource into soft requests for the hdfs_primary_rack, hdfs_secondary_rack, and hdfs_blk* resources. In order to do the conversion, this JSV must be able to contact the Namenode for the HDFS cluster. TODO: Make it possible to make the block and rack requests hard instead of soft.
