[FLINK-2525]Add configuration support in Storm-compatibility
- enable config can used in Spouts.open() and Bout.prepare().
Example like this:
public static void main(final String[] args) {
String topologyId = "Streaming WordCount";
final FlinkTopologyBuilder builder = new FlinkTopologyBuilder();
...
final Config conf = new Config();
conf.put("wordsFile", "/home/user/");
conf.put("delimitSize", 1024);
final FlinkLocalCluster cluster = FlinkLocalCluster.getLocalCluster();
cluster.submitTopology(topologyId, conf, builder.createTopology());
Utils.sleep(10 * 1000);
cluster.killTopology(topologyId);
cluster.shutdown();
}
public class WordReader implements IRichSpout {
....
public void open(Map conf, TopologyContext context,
SpoutOutputCollector collector) {
try {
this.context = context;
this.fileReader = new FileReader(conf.get("wordsFile"));
} catch (FileNotFoundException e) {
throw new RuntimeException("Error reading file
["+conf.get("wordFile")+"]");
}
this.collector = collector;
}
}
public final class StormBoltTokenizer implements IRichBolt {
....
public void prepare(Map stormConf, TopologyContext context,
OutputCollector collector) {
this.delimitSize = stormConf.get("delimitSize");
this.collector = collector;
}
}
