I tired to build a trident topology as the official trident tutorial told
http://storm.incubator.apache.org/documentation/Trident-tutorial.html
the code is simple, but I don’t have a cluster so I wanna run this topology
with local cluster with a local drpc, but I don’t know how, any idea?
my code is here---------------
TridentTopology topology;
topology = new TridentTopology();
TridentState wordCounts = topology.newStream("spout1", spout)
.each(new Fields("sentence"), new Split(), new Fields("word"))
.groupBy(new Fields("word"))
.persistentAggregate(new MemoryMapState.Factory(), new Count(),
new Fields("count"))
.parallelismHint(10);
topology.newDRPCStream("words")
.each(new Fields("args"), new Split(), new Fields("word"))
.groupBy(new Fields("word"))
.stateQuery(wordCounts, new Fields("word"), new MapGet(), new
Fields("count"))
.each(new Fields("count"), new FilterNull())
.aggregate(new Fields("count"), new Sum(), new Fields("sum"))
