zk=3,NOTIN,NODE,zk:hbase=5,IN,RACK,zk:spark=7,CARDINALITY,NODE,hbase,1,3{code}
 
 * place 5 containers with tag “hbase” with affinity to a rack on which containers with
tag “zk” are running (i.e., an “hbase” container should{color:#FF0000} not{color}
be placed at a rack where an “zk” container is running, given that “zk” is the TargetTag
